Imagine we have two functions named foo and bar that each take in an int and return a bool. We don't know what these functions do. Either of them could do something like... Return True if the number is even and False if it's odd . Return True if the number has a 0-4 in the 1s place and a False otherwise . Return True if the number is palindromic (e.g., 343, 7557, 2) and False otherwise Return True if the number is prime and False otherwise Without knowing what the functions do, we want to find the smallest nonnegative integer that causes both foo and bar to return True when it's passed in. What type of loop is most appropriate for this search? while True: (with break) while : for x in : O for i in range(len(iterable)):
