Kitty [74]

Answer:

The program in Python is as follows:

import math

def integer_to_reverse_binary(integer_value):

   remainder = ""

   while integer_value>=1:

       remainder+=str(integer_value % 2)

       integer_value=math.floor(integer_value/2)

   reverse_string(remainder)

def reverse_string(input_string):

   binaryOutput=""

   for i in range(len(input_string)-1,-1,-1):

       binaryOutput = binaryOutput + input_string[i]

   print(binaryOutput)

integer_value = int(input("Enter a Number : "))

integer_to_reverse_binary(integer_value)

Explanation:

This imports the math module

import math

This defines the integer_to_reverse_binary function

def integer_to_reverse_binary(integer_value):

This initializes the remainder to an empty string

   remainder = ""

This loop is repeated while the integer input is greater than or equal to 1

   while integer_value>=1:

This calculates the remainder after the integer value is divided by 2

       remainder+=str(integer_value % 2)

This gets the floor division of the integer input by 2

       integer_value=math.floor(integer_value/2)

This passes the remainder to the reverse_string function

   reverse_string(remainder)

The reverse_string function begins here

def reverse_string(input_string):

This initializes the binaryOutput to an empty string

   binaryOutput=""

This iterates through the input string i.e. the string of the remainders

   for i in range(len(input_string)-1,-1,-1):

This reverses the input string

       binaryOutput = binaryOutput + input_string[i]

This prints the binary output

   print(binaryOutput)

<u>The main begins here</u>

This gets input for integer_value

integer_value = int(input("Enter a Number : "))

This passes the integer value to the integer_to_reverse_binary function

integer_to_reverse_binary(integer_value)
