Write a recursive method that returns the number of 1’s in the binary representation of N. Use the fact that this is equal to the number of 1’s in the representation of N/2, plus 1, if N is odd
Answers
Answer:
Here is the recursive method NoOfOnes :
public static int NoOfOnes(int N) { // method that takes number N as argument and returns the number of 1’s in the binary representation of N
if(N==0) { //base case 1
return 0; } //if the value of N is equal to 0 then method returns 0
else if(N==1){ //base case 2
return 1; } // if the value of N is equal to 1 then method returns 1
else if(N%2==1) { //if N is odd (recursive case)
return NoOfOnes(N/2)+1; } //calls method recursively and divides N by 2 plus 1
else{ //when N i even (recursive case)
return NoOfOnes(N/2); } } //calls method recursively and divides N by 2 to return number of 1's in binary representation of N
Explanation:
Here is the complete JAVA program:
import java.util.Scanner; //to take input from user
public class Main {
public static int NoOfOnes(int N) {//the method that takes number N as argument and returns the number of 1’s in the binary representation of N
if(N==0) { //base case 1
return 0; }
else if(N==1){//base case 2
return 1; }
else if(N%2==1) {//recursive case when N is odd
return NoOfOnes(N/2)+1; }
else{ //recursive case when N is even
return NoOfOnes(N/2); } }
public static void main(String[] args) { //start of main function
Scanner scan = new Scanner(System.in); //creates object of Scanner
System.out.print("Enter n: ");//prompts user to enter value of N
int n = scan.nextInt(); //reads the value of n from use
System.out.print("number of 1’s in the binary representation of " +n+" is: "+NoOfOnes(n)); } } //displays the number of 1’s in the binary representation of n
i will explain the working of the function with an example
Lets say N = 6
if(N==0) this statement evaluates to false as N is not 0
else if(N==1 this statement also evaluates to false as N is not 1
else if(N%2==1) this statement also evaluates to false because N is not odd. If we take modulo of 6 by 2 then the remainder is 0 because 6 is completely divisible by 2 so N = 6 is an even number. So the else part is executed:
else{
return NoOfOnes(N/2);}
This statement calls NoOfOnes recursive by passing N/2 to the method. So this becomes:
return NoOfOnes(6/2)
6/2 = 3
NoOfOnes(3)
Now this method is called again with the value of N = 3. Since 3 is an odd number so the recursive case of odd N is executed:
else if(N%2==1) {
return NoOfOnes(N/2)+1; }
NoOfOnes(3/2)+ 1
NoOfOnes(1) + 1
Now the method is called again with value of N=1. The base case 2 is executed because N==1 which returns 1
else if(N==1){
return 1; }
So this becomes
NoOfOnes(1) + 1
1 + 1
= 2
So the method return 2 as the number of 1’s in the binary representation of N = 6
Hence the output of the above program with N = 6 is
number of 1’s in the binary representation of 6 is: 2

Write a program that reads in any number of MyStrings of characters from the user and determines if each MyString is a palindrome. The user will terminate each MyString by pressing the return (or enter) button. The user will indicate that there are no more MyStrings by entering "quit". The function must be recursive and must not call any other functions.
Answers
Answer:
Here is the recursive function:
bool isPalindrome(string& MyString,int start, int end){ // function that takes as argument a string and two arguments that are bounds indices
while(start < MyString.length() && !isalpha(MyString[start])){ //while loop continues to execute as long as start does not exceed the length of the string AND does not point to a alphabetic letter
start++; } // increments start by 1 moving it to point the next character
while(end >= 0 && !isalpha(MyString[end])){ //while loop continues to execute as long as end does not gets less than 0 AND does not point to a alphabetic letter
end--; } // decrements end by 1 moving it to point the next character backwards
if(start > end){ //the base case
return true;
} else { //recursive case
return ( ( toupper(MyString[start]) == toupper(MyString[end]) ) && isPalindrome(MyString,start+1,end-1)); } } //The recursive case is to AND the result of comparing the alphabetic letters at start and end with result of the function (called recursively) after without both of the letters
Explanation:
Here is the complete C++ program:
#include <iostream> //to use input output functions
#include <cctype> //functions to manipulate characters
using namespace std; //to identify objects as cin cout
bool isPalindrome(string&,int start, int end); // function prototype
int main(){ //start of main function
string MyStrings; //declare a string type variable to hold string of characters
cout<<"Enter a string : "; //prompts user to enter a string
getline(cin,MyStrings ); //gets and reads the string from user
while(MyStrings != "quit"){ // continues to take input from user until user enters quit
if(isPalindrome(MyStrings ,0,MyStrings.length()-1)== true){ //calls function that checks if the string is a palindrome
cout<<MyStrings<<" is a Palindrome\n";} //if the input string is a palindrome then display this message
else
{cout<<MyStrings<<" is not a Palindrome\n";} //if the input string is not a palindrome then displays this message
cout<<"Enter a string : "; //prompts user to enter a string
getline(cin,MyStrings); } } //reads a string from user
bool isPalindrome(string& MyString,int start, int end){ //function definition
while(start < MyString.length() && !isalpha(MyString[start])){
start++; }
while(end >= 0 && !isalpha(MyString[end])){
end--; }
if(start > end){
return true;
} else {
return ( ( toupper(MyString[start]) == toupper(MyString[end]) ) && isPalindrome(MyString,start+1,end-1)); } }
I will explain the working of the function:
First the start variable is pointed to the start of the MyString and the end variable points to the last character of MyString
while(start < MyString.length() && !isalpha(MyString[start]))
The above statement has a while loop which continues to execute as long as start does not exceed the string length and it does not point to a letter. It has a AND logical operator that means both the above condition have to be true in order to continue this while loop. Here isalpha() method is used that checks if the letter/character of MyString is an alphabet or not. At each iteration start is incremented to 1 to point the next character of MyString.
while(end >= 0 && !isalpha(MyString[end]))
The above statement has a while loop which continues to execute as long as end does not becomes less than 0 and it does not point to a letter, Here isalpha() method is used that checks if the letter/character of MyString is an alphabet or not. At each iteration end is decremented to 1 to point the next character of MyString in backward or in reverse order.
if(start > end){
The above statement is a base case which is the IF condition that checks if the start is greater than end. This basically shows that there are no more alphabetic characters and this base case returns true as it reads the same from both sides.
else {
return ( ( toupper(MyString[start]) == toupper(MyString[end]) ) && isPalindrome(MyString,start+1,end-1)); } }
The above statement is a recursive part. It uses AND logical operator and compares the characters at start and end with the result of the function after excluding both of the characters pointed by start and end.

Consider sorting n numbers stored in array A by first finding the smallest element of A and exchanging it with the element in A[1]. Then find the second smallest element of A, and exchange it with A[2]. Continue in this manner for the first n − 1 elements of A. Write pseudocode for this algorithm, which is known as selection sort. What loop invariant does this algorithm maintain? Why does it need to run for only the first n − 1 elements, rather than for all n elements? Give the best–case and worst–case running times of selection sort in Θ–notation.
Answers
Answer:
1. create the first array A
2. create the second array A1, the same length as array A.
3. create a loop to iterate over both arrays for a number of times specific to the length of the arrays, with a condition to get and pop only the minimum value of which arrays for every loop.
4. save both items to "a" for minimum value A and "b" for minimum value A1.
5. call a function to push the "a" variable value to A1 and "b" variable value to the array A.
Explanation:
This code would interchange the values of both arrays, the best-case scenario for the code is O( n ) where n is the number of items in both arrays and worst is the best-case multiplied by the number of time to compare all the items with the minimum value.

how to write a function that counts the letters in a string in C?
Answers
Answer:
Here is the C function that counts the letters in a string:
int LetterCount(char string[]){ //function to count letters in a string passed as parameter
string[100]; // char type string with size 100
int i, letters; // letter variable stores the count for no. of letters in string
i = letters = 0; //initialize variables i and letters to 0
while (string[i] != '\0') { // loop iterates through the entire string until end of string is reached
if( (string[i] >= 'a' && string[i] <= 'z') || (string[i] >= 'A' && string[i] <= 'Z') ) { // if condition checks the letters in the string
letters++; } // increments 1 to the count of letters variable each time a letter is found in the string
i++; } //increments value of i to move one character forward in string
printf("Number of Letters in this String = %d", letters); // displays the number of letters in the string
return 0; }
Explanation:
Here the question means that the function should count the letters in a string. So the letters are the alphabets from a to z and A to Z.
Here is the complete program:
#include <stdio.h> // to use input output functions
int LetterCount(char string[]){ // method that takes a character string as parameter and counts the letters in the string
string[100];
int i, letters;
i = letters = 0;
while (string[i] != '\0') {
if( (string[i] >= 'a' && string[i] <= 'z') || (string[i] >= 'A' && string[i] <= 'Z'))
{letters++; }
i++; }
printf("Number of Alphabets in this String = %d", letters);
return 0;}
int main(){ // start of main function
char string[100]; //declares a char array of string
printf("Please Enter a String : "); //prompts user to enter a string
fgets(string,100,stdin); //get the input string from user
LetterCount(string); } // calls method to count letters in input string
I will explain this function with an example
Lets suppose the user input "abc3" string
string[100] = "abc3"
Now the function has a while loop that while (string[i] != '\0') that checks if string character at i-th position is not '\0' which represents the end of the character string. As value of i = 0 so this means i is positioned at the first character of array i.e. 'a'
At first iteration:
i = 0
letter = 0
if( (string[i] >= 'a' && string[i] <= 'z') || (string[i] >= 'A' && string[i] <= 'Z') ) if condition checks if the character at i-th position of string is a letter. As the character at 0-th position of string is 'a' which is a letter so this condition evaluates to true. So the statement letter++ inside if condition executes which increments the letter variable to 1. So the value of letter becomes 1. Next statement i++ increments the value of i to 1. So i becomes 1. Hence:
i = 1
letter = 1
At second iteration:
i = 1
letter = 1
if( (string[i] >= 'a' && string[i] <= 'z') || (string[i] >= 'A' && string[i] <= 'Z') )
if condition checks if the character at i-th position of string is a letter. As the character at 1st position of string is 'b' which is a letter so this condition evaluates to true. So the statements letter++ inside if condition and i++ executes which increments these variables to 1. Hence:
i = 2
letter = 2
At third iteration:
i = 2
letter = 2
if( (string[i] >= 'a' && string[i] <= 'z') || (string[i] >= 'A' && string[i] <= 'Z') )
if condition checks if the character at i-th position of string is a letter. As the character at 2nd position of string is 'c' which is a letter so this condition evaluates to true. So the statements letter++ inside if condition and i++ executes which increments these variables to 1. Hence:
i = 3
letter = 3
At fourth iteration:
i = 3
letter = 3
if( (string[i] >= 'a' && string[i] <= 'z') || (string[i] >= 'A' && string[i] <= 'Z') )
if condition checks if the character at i-th position of string is a letter. As the character at 3rd position of string is '3' which is not a letter but a digit so this condition evaluates to false. So the statement letter++ inside if condition does not execute. Now i++ executes which increments this variable to 1. Hence:
i = 4
letter = 3
Now the loop breaks because while (string[i] != '\0') condition valuates to false as it reaches the end of the string.
So the statement: printf("\n Number of Letters in this String = %d", letters); executes which prints the value of letters on the output screen. Hence the output is:
Number of Letters in this String = 3

Answers
Answer:
A private IP address should be implemented but a PAT and a static NAT should be configured for the computers and the intermediate devices respectively.
Explanation:
There are two types of IP addresses, they are public and private addresses. The public address is an IP4 address routable on the internet while the private address is not routable.
Internet service providers do charge for the use of public IP addresses they render, which can be very costly. To reduce the company's expenses on the internet, the company is networked with private addresses and are mapped for network address translation ( NAT) which assigns a public global address to devices accessing the internet.

Answers
Answer:
A structured chart is a sequential representation of program design
Explanation:
It is true that a real-time system which is a term to describe an operating system working in relation to real-time is actually a form of the online system. Hence, option B is not correct.
It is also true that Batch totals are not incorporated while designing real-time applications because Batch Data processing is carried out in a separate manner and at a time when the computer is free. Thus Option C is not Correct
It is also true that 4GL which stands for Forth generation programming language is used for application prototyping. Again Option D is not Correct.
However, a structured chart is not a sequential representation of program design, but rather a break down to the infinitesimal module in the program design. Hence, option A is the correct answer.

Analyze carefully and explicitly the time complexity of A in terms of the input size. Show all steps. Is A a polynomial time algorithm? Justify your answer.
Answers
Answer:
The Following are the solution to this question:
Explanation:
In Option a:
In the point (i) [tex]\Omega[/tex] is transitive, which means it converts one action to others object because if [tex]\Omega(f(n))=g(n)[/tex] indicates [tex]c.g(n)<=f(n)[/tex]. It's true by definition, that becomes valid. But if [tex]\Omega(g(n))=h(n)[/tex], which implies [tex]c.h(n)<=g(n)[/tex]. it's a very essential component. If [tex]c.h(n) < = g(n) = f(n) \[/tex]. They [tex]\Omega(f(n))[/tex] will also be [tex]h(n)[/tex].
In point (ii), The value of [tex]\Theta[/tex] is convergent since the [tex]\Theta(g(n))=f(n)[/tex]. It means they should be dual a and b constant variable, therefore [tex]a.g(n)<=f(n)<=b.g(n)[/tex] could only be valid for the constant variable, that is [tex]\frac{1}{a}\ \ and\ \ \frac{1}{b}[/tex].
In Option b:
In this algorithm, the input size value is equal to 1 object, and the value of A is a polynomial-time complexity, which is similar to its outcome that is [tex]O(n^{2})[/tex]. It is the outside there will be a loop(i) for n iterations, that is also encoded inside it, the for loop(j), which would be a loop[tex](n^{2})[/tex]. All internal loops operate on a total number of [tex]N^{2}[/tex] generations and therefore the final time complexity is [tex]O(n^{2})[/tex].

If a file is found then the program displays the message File exists and add 1 to the count variable each time a file is found. If all the files are found then the program returns the count as 4 otherwise the program display the number of files found by displaying the computed final value of count in the output. Lets say all the files are found then the output of the above program is:
autoexec.bat autoexec.bat File Exists
CompareFolders.java CompareFolders.java File Exists
FileStatistics.class File Exists
Hello.doc Hello.doc File Exists
4 of the files exist

Answers
Answer:
The best solution.
Explanation:
In the operations and management of systems such as manufacturing, transport, government, network, service systems, we encounter various type of challenges and problems. These challenges and problems must be fixed or resolved as soon as possible in order to restore normal operations, as well as ensuring that the solution mitigates the occurrence of such problems in the future.
Hence, an optimal solution to an Operations problem will yield the best solution because it gives the maximum functionality. For instance, an optimal solution is considered to be the best solution because it gives the least cost, effective and efficient or gives the most profit.
2.13) A simple rule to estimate your ideal body weight is to allow 110 pounds for the first 5 feet of height and 5 pounds for each additional inch. Write a program that reads the data in the file and outputs the full name and ideal body weight for each person. In the next chapter, you will learn about loops, which allow for a more efficient way to solve this problem.
Answers
Answer:
import csv
def ideal_weight( filename ):
with open( "filename", "r" ) as file:
for row in csv.DictReader( file):
print ( "Name of person: ",row["name"] )
person_weight = ( 110 * row["height"] )/ 5
print ( "Ideal weight: ", person_weight )
Explanation:
The python source code above is a function which recieves a csv file argument, opens the file and reads each row an ordered dictionary. The function prints the name of each person in the file and their ideal weight.

In an event, it is when an object moves from a prior state to a subsequent state.
a. True
b. False
Answers
Answer:
a. True
Explanation:
Objects suffer inertia before a transition is achieved. Transition is the movement of an object from one state to another. But, this transition does not happen on its own. It is usually triggered by an event or series of events. This means that when the object moves from its prior state to a subsequent state, an event must have occurred to trigger the transition. Objects, therefore, depend on events or an outside force to remove their inertia. They are usually in a state of inertia until an outside stimulus stimulates them with some momentum.
