Your program must define and call the following two functions. the function integer_to_reverse_binary() should return a string of 1's and 0's representing the integer in binary (in reverse). the function reverse_string() should return a string representing the input string in reverse. def integer_to_reverse_binary(integer_v alue) def reverse_string(input_string) note: this is a lab from a previous chapter that now requires the use of a function.
