Given a m*n matrix ,print it in spiral form.
eg:
1 2 3 4 5 6 7 8 9 10
11 12 13 14 15
16 17 18 19 20print it in spiral form
Given an integer n, write a function that returns count of trailing zeroes in n!. Examples: Input: n = 5 Output: 1 Factorial of 5 is 20 which has one trailing 0. Input: n = 20 Output: 4 Factorial of 20 is 2432902008176640000 which has 4 trailing zeroes. Input: n = 100 Output: 24
