The right-most non zero digit in N!
Question:
Write a program which shows the right-most non-zero
digit in N! where N is a positive integer less
than 32000. For example:
- 5!=120 ==> right-most non zero digit is 2
- 7!=5040 ==> right-most non zero digit is 4
- 10!=368800 ==> right-most non zero digit is 8
Input specification
You are given an integer (N) where is 1 ≤
N ≤ 32,000.
Output specification
