Write a python function to compute a certain number to a given power. The program should continue asking the user for number and power and display the result until the user enters 0 as the number. Note: don't use the power function of Python. Compute the power using a for or a while loop.
Answers
while True:
number = int(input("input the number: "))
exponent = int(input("input the exponent : "))
if number == 0:
break
else:
result = 1
while exponent != 0:
result *= number
exponent-=1
print("Answer = " + str(result))
we are asked not to use the power function of python. The question wants us to use a for or a while loop to compute the power.
The while loop makes sure the user is always asked to input the number and an exponent.
If the users number equals 0, the while loop will break.
Else the code will find the power of the number.
Finally, we print the answer if the user number is not zero

Consider the following class. public class ClassicClass { private static int count = 0; private int num; public ClassicClass() { count++; num = count; } public String toString() { return count + " " + num; } } What is printed when the following code in the main method of another class is run? ClassicClass a = new ClassicClass(); ClassicClass b = new ClassicClass(); ClassicClass c = new ClassicClass(); System.out.println(a + ", " + b + ", " + c);
Answers
The the code in the main method is run, it will print
"3 1, 3 2, 3 3"
The static/class field count stores the number of instances of the class created. count is always incremented when the instance constructor is called.
The instance field num acts like an identifier/serial number for the instance created. When the constructor is called, the current count is stored in the num field of the instance.
Each instance's toString( ) method will output the total count (from count) and the serial of the instance (from num).
When the code runs in the main method, it creates three instances (making count==3), so that we have
a = {count: 3, num: 1}b = {count: 3, num: 2}c = {count: 3, num: 3}and implicitly calls toString( ) in the println method for each of the three instances to produce the following output
"3 1, 3 2, 3 3"

In packet switching, there are two rather similar approaches as well, namely, circuit switching and package switching. Discuss the similarities and differences in these two problem domains and the corresponding approaches g
Answers
The similarity between the two systems is the ability to connect many different communication devices and transfer data between a sender and a receiver. The main difference is the need for a connection for both to work.
We can arrive at this answer because:
Circuit and package quotation is very important for the connections of different communication devices.Furthermore, these two systems are used efficiently when a data transfer is required.However, even being used for the same purposes, they have many differences between them.The biggest difference is the need for a connection, as package switching is done without the need for a connection, while circuit switching needs a connection to act.In addition, circuit switching is more widely used because of its ability to transfer data from one point to another via message transfer, while package switching is used when circuit switching is not available as it does the sending data more slowly across one drive.

6-Write a BNF description of the precedence and associativity rules defined for the expressions in Problem 9 - chapter 7 of the textbook . Assume the only operands are the names a,b,c,d, and e.
Answers
The BNF description, or BNF Grammar, of the precedence and associativity rules are
[tex]<identifier>\text{ }::=a|b|c|d|e[/tex]
[tex]<operand>\text{ }::=\text{ }NUMBER\text{ }|\text{ }<Identifier>[/tex]
[tex]<factor>\text{ }::=\text{ }<operand>|\text{ }-<operand>|\text{ }(<expression>)[/tex]
[tex]<power>\text{ }:=\text{ }<factor>\text{ }|\text{ }<factor>\text{**} <power>[/tex]
[tex]<term>\text{ }::=\text{ }<power>\text{ }\\|\text{ }<term>*<power>\text{ }\\|\text{ }<term>/<power>\\\\<expression>\text{ }::=\text{ }<term>\text{ }\\|\text{ }<expression>+<term>\text{ }\\|\text{ }<expression>-<term>[/tex]
BNF, or Backus-Naur Form, is a notation for expressing the syntax of languages. It is made up of a set of derivation rules. For each rule, the Left-Hand-Side specifies a nonterminal symbol, while the Right-Hand-side consists of a sequence of either terminal, or nonterminal symbols.
To define precedence in BNF, note that the rules have to be defined so that:
A negation or bracket matches first, as seen in the nonterminal rule for factorA power matches next, as seen in the rule defining a factorA multiplication, or division expression matches next, as seen in the rule defining a termFinally, addition, or subtraction match, as seen in the rule defining an expression.To make sure that the expression is properly grouped, or associativity is taken into account,
Since powers associate to the right (that is, [tex]x \text{**} y\text{**}z=x \text{**} (y\text{**}z)\text{ and not }(x \text{**} y)\text{**}z[/tex]), the rule defining power does this[tex]<power>\text{ }:=\text{ }<factor>\text{ }|\text{ }<factor>\text{**} <power>[/tex]
and not
[tex]<power>\text{ }:=\text{ }<factor>\text{ }|\text{ }<power>\text{**}<factor>[/tex]
Since multiplication/division are left associative (that is, [tex]x \text{*} y\text{*}z=(x \text{*} y)\text{*}z[/tex]), the rule defining a term takes this into account by specifying its recursion on the right of the operators like so;[tex]<term>\text{ }::=\text{ }<power>\text{ }\\|\text{ }<term>*<power>\text{ }\\|\text{ }<term>/<power>[/tex]
Also, addition and subtraction are left associative (that is, [tex]x \text{+} y\text{+}z=(x \text{+} y)\text{+}z[/tex]), the rule defining an expression takes this into account as seen below[tex]<expression>\text{ }::=\text{ }<term>\text{ }\\|\text{ }<expression>+<term>\text{ }\\|\text{ }<expression>-<term>[/tex]

Write a program that lists all ways people can line up for a photo (all permutations of a list of strings). The program will read a list of one word names (until -1), and use a recursive method to create and output all possible orderings of those names separated by a comma, one ordering per line.
Answers
The solution is the recursive Python 3 function below:
########################################################
def allNamePermutations(listOfNames):
# return all possible permutations of listOfNames
if len(listOfNames) == 0 or len(listOfNames) == 1:
# base case
return [listOfNames]
else:
# recursive step
result_list = [ ]
remaining_items = [ ]
for firstName in listOfNames:
remaining_items = [otherName for otherName in listOfNames if
(otherName != firstName)]
result_list += concat(firstName,
allNamePermutations(remaining_items))
return result_list
#######################################################
How does the above function work?
As with all recursive functions, this one also has a base case, and a recursive step. The base case tests to make sure the function terminates. Then, it directly returns a fixed value. It does not make a recursive call.
In the case of this function, the base case checked listOfNames to see if it was empty or only had one name. If any of the conditions were satisfied, a new list containing listOfNames is returned.
The recursive step is where the function allNamePermutations() calls itself recursively. The recursive step handles the case where listOfNames has more than one item. This step first iterates over each name in listOfNames, and then does the following;
Gets a name in listOfNameGets a list of other names in listOfNamesCalls allNamePermutations() on the list of other names to get a list of permutation of the other names.(By first getting the list of other names before passing it into
allNamePermutations(), we make sure the recursive step eventually
terminates. This is because we are passing a smaller list each time
we make the recursive call.)
Inserts the current name in front of each permutationAdds the results to the result list to be returned laterAfter the iteration, it returns the result list which will now contain all permutations of the names in the list.
The concat function is defined below
##################################################
def concat(name, listOfNameLists):
# insert name in front of every list in listOfNameLists
result_list = [ ]
for nameList in listOfNameLists:
nameList.insert(0, name)
result_list.append(nameList)
return result_list
#####################################################
If we run the sample test case below
####################################
name_list = ['Adam', 'Barbara', 'Celine']
allNamePermutations(name_list)
####################################
the following output is produced
[['Adam', 'Barbara', 'Celine'],
['Adam', 'Celine', 'Barbara'],
['Barbara', 'Adam', 'Celine'],
['Barbara', 'Celine', 'Adam'],
['Celine', 'Adam', 'Barbara'],
['Celine', 'Barbara', 'Adam']]

Answers
Answer:
While statements determine whether a statement is true or false. If what’s stated is true, then the program runs the statement and returns to the first step. If what’s stated is false, the program exits the while and goes to the next statement. An added step to while statements is turning them into continuous loops. If you don’t change the value so that the condition is never false, the while statement becomes an infinite loop.
If statements are the simplest form of conditional statements, statements that allow us to check conditions and change behavior/output accordingly. The part of the statement following the if is called the condition. If the condition is true, the instruction in the statement runs. If the condition is not true, it does not. The if statements are also compound statements. They have a header (if x) followed by an indented statement (an instruction to be followed is x is true). There is no limit to the number of these indented statements, but there must be at least one.
