Problem

Given a string SS, write a program that computes the RIPEMD-160 hash of SS. RIPEMD-160 is a hash function that reduces a byte sequence of any length to a 160-bit hash value. Treat SS as a sequence of ASCII bytes.

Input

The first line contains the string SS. SS consists only of uppercase letters, lowercase letters, and digits, and its length is at most 50.

Output

On the first line, print the RIPEMD-160 hash of SS as 40 lowercase hexadecimal digits.
