g Add a throw statement to the processNumbers function that throws the message "An element in the list is not a number." if one of the elements in toProcess is not a number. Hint: The function isNaN() returns true if the parameter is not a number.
Answer and Explanation:
function processNumbers(alist){
var Ourarray= new array(alist);
Ourarray.foreach(
if(isNaN()){
Console.log( "An element in the list is not a number."};
break;
}
}
processNumbers(alist)
From the above, we have defined a function that takes an array parameter(the following array variable will make sure of that). We test each element in the array using foreach array function. The for each function runs the if statement and if isNan is true for each of the elements in the array.

A function that uses the binary search algorithm to search for a value in an array a. repeatedly divides the elements into the number of segments you specify and discards the segments that don’t have the value until the value is found and a pointer to the element is returned b. repeatedly divides the elements in half and discards the half that doesn't have the value until the value is found and a pointer to the element is returned c. repeatedly divides the sorted elements in half and discards the half that doesn't have the value until the value is found and the index of the element is returned d. repeatedly divides the elements into the number of segments you specify and discards the segments that don’t have the value until the value is found and the index of the element is returned
Answer:
c. repeatedly divides the sorted elements in half and discards the half that doesn't have the value until the value is found and the index of the element is returned.
Explanation:
When binary search is used for algorithm search then the work is searched in the sorted array. There arrays are divided in half and then half of the elements are discarded who does not have value. The search does not completes until it founds the value and index of the element.

cpp Write a program that first gets a list of integers from input. The input begins with an integer indicating the number of integers that follow. Then, get the last value from the input, which indicates a threshold. Output all integers less than or equal to that last threshold value. Ex: If the input is:
Answer:
#include <iostream>
int main() {
// The length of the list
int l;
// The array containing the numbers
int *list;
// Threshold, last value in array
int thresh;
// Read in first value and create an array with the size of that value
scanf("%d", &l);
list = (int*) malloc(l * sizeof(int));
for(int i = 0; i < l; i++) {
scanf("%d", &list[i]);
}
thresh = list[l - 1];
// Print the values
for(int i = 0; i < l - 1; i++) {
if (list[i] <= thresh) {
printf("%d ", list[i]);
}
}
printf("\n");
free(list);
}
Explanation:
The program assumes at least two values are provided. The length of the list and the threshold.
We first read in an integer, and find out how many more integers we need to read. We create an array with the appropriate size, and loop through to fill the array with values. We know the last value is the threshold, and so we do one more loop to compare the values in the array with the threshold.

Which of the given assertion methods will return true for the code given below? Student student1 = new Student(); Student student2 = new Student(); Student student3 = student1;
The Student class is as follows.
public class Student{
private String name;
}
a. assertEquals(student1, student2);
b. assertEquals(student1, student3);
c. assertSame(student 1, student3);
d. assertSame(student1, student2);
Answer:
The true statements are :
A. assertEquals(student1,student2)
C. assertSame(student1,student3)
Explanation:
AssertEquals() asserts that the objects are equal, but assertSame() asserts that the passed two objects refer to the same object or not, if found same they return true, else return false.
Methods are collections of named code segments that are executed when evoked
The assertion method that will return true for the given code is: assertEquals(student1,student2)
The code segment is given as:
Student student1 = new Student();
Student student2 = new Student();
Student student3 = student1;
In Java, the assertEquals() method returns true if two objects have equal values.
Assume student1 and student2 have equal values, the statement assertEquals(student1,student2) will return true

Why are data silos problematic?
Answer:
Hampers collaboration
Resource wastage
Lack of data integrity
Explanation:
Data silos comes into play When different departments of an orgainiziations independently collects data needed for its operations. The finance, HR, administrative departments and so on collects their data and keeps it to themselves. As a result there is a repetitive and needless gathering and storage of already existing data, that is the data required by one group will have to be gathered again while it currently exists with another group. This leads to inefficient resource management and wastage. This practice also leads to data integrity as data stored differently across departments becomes inconsistent and less accurate over time. Team work and collaboration is gradually eroded as each group continues to hold on to its resources which poses a problem towards organizational growth.

Write a C++ function using recursion that returns the Greatest Common Divisor of two integers. The greatest common divisor (gcd) of two integers, which are not zero, is the largest positive integer that divides each of the integers. For example, the god of 8 and 12 is 4.
Answer:
The function is as follows:
int gcd(int num1, int num2){
if (num2 != 0){
return gcd(num2, num1 % num2);}
else {
return num1;}
}
Explanation:
This defines the function
int gcd(int num1, int num2){
This is repeated while num2 is not 2
if (num2 != 0){
This calls the function recursively
return gcd(num2, num1 % num2);}
When num2 is 0
else {
This returns the num1 as the gcd
return num1;}
}
The Curiosity Rover has recently landed on Mars and likes to send Twitter updates on its progress. If a tweet is posted 10 minutes after it was sent, how far is Curiosity from Earth? (Assume there is no network lag.)
Answer:
1.8 * 10^11 m
Explanation:
Given that :
Time taken for tweet to me posted after been sent, t = 10 minutes
t in seconds :
60 seconds = 1 minute
10 minutes = (10 * 60) = 600 seconds
Tweet sent will br transmitted at the speed of light, c = 3 * 10^8 m/s
Recall :
Speed = distance / time
Distance = speed * time
Distance of Curiosity from Earth = (3 * 10^8 * 600)
Distance of curiosity from earth = 1.8 * 10^11 m
Define a generic function called CheckOrder() that checks if four items are in ascending, neither, or descending order. The function should return -1 if the items are in ascending order, 0 if the items are unordered, and 1 if the items are in descending order. The program reads four items from input and outputs if the items are ordered. The items can be different types, including integers, strings, characters, or doubles. Ex. If the input is: bat hat mat sat 63.2 96.5 100.1 123.5 the output is: Order: -1 Order: -1
Answer and Explanation:
Using javascript:
/*This function checks only for ascending order. This function cannot check ascending orders for strings, just integers or floats.*/
function CheckOrder(){
var takeinput= prompt("please enter four numbers")
var makeArray= takeinput.split("");
var numArray= new Array(4);
numArray= [makeArray];
var i;
for(i=0; i<=numArray.length; i++){
var nowElem= numArray[i];
if(numArray[1]){
Alert("let's check to see");
}
else if(
nowElem > numArray[i--]){
Alert("might be ascending order");
if(numArray[i]==numArray[2]){
var almosthere=numArray[2]
}
else if(numArray[i]==numArray[3]){
var herenow=numArray[3];
if(almosthere>herenow){
Alert("numbers are in ascending order");
}
}
}
else(
Console.log("there are no ascending orders here")
)
}
The function above can further be worked on to also check for descending order of four numbers(can also be further developed to check for strings). You need just tweak the else if and nested else if statements thus :
else if(
nowElem < numArray[i--]){
Alert("might be descending order");
if(numArray[i]==numArray[2]){
var almosthere=numArray[2]
}
else if(numArray[i]==numArray[3]){
var herenow=numArray[3];
if(almosthere<herenow){
Alert("numbers are in descending order");
}
}
}

Answer:
Defense in Depth (DiD).
Explanation:
Cyber security can be defined as preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.
Defense in Depth (DiD) can be defined as a concept or framework in cyber security that typically involves the process of layering multiple defensive mechanisms and security control throughout an information technology (IT) system, so as to prevent data theft or an unauthorized access to user data.
Basically, this cyber security technique is designed such that when a layer of the defensive mechanism fails, another security layer step in to mitigate and prevent the attack. Thus, it causes redundancy when an attacker exploits a vulnerability in a system, a breach of security or when one of the security layers fail.
