Write a python

program that takes in a positive integer as input, and outputs a string of $1\text{'}$s and $0\text{'}$s representing the integer in binary.

The program must define and call the following two functions. Define a function named int$\_$to$\_$reverse$\_$binary$()$ that takes an integer as a parameter and returns a string of $1\text{'}$s and $0\text{'}$s representing the integer in binary $($in reverse$).$ Define a function named string$\_$reverse$()$ that takes an input string as a parameter and returns a string representing the input string in reverse.

def int$\_$to$\_$reverse$\_$binary$($integer$\_$value$)$

def string$\_$reverse$($input$\_$string$)$
