For an integer N find the number of trailing zeroes in N!.
N = 5Output:
5! = 120 so the number of trailing zero is 1.
N = 4Output:
4! = 24 so the number of trailing zero is 0.
You don't need to read input or print anything. Your task is to complete the function trailingZeroes() which take an integer N as an input parameter and returns the count of trailing zeroes in the N!.
Expected Time Complexity: O(logN) Expected Auxiliary Space: O(1)
