6.24 LAB: Convert to binary - functions
Write a program that takes in a positive integer as input, and outputs a string of 1's and 0's representing the integer in binary. For an integer x, the algorithm is:
As long as x is greater than 0
Output x % 2 (remainder is either 0 or 1)
x = x // 2
Note: The above algorithm outputs the 0's and 1's in reverse order. You will need to write a second function to reverse the string.
Ex: If the input is:
6
the output is:
110
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's and 0'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.
