Description

When storing IP addresses in a database, for example, $192.168.1.1$ requires 11 characters. However, if we convert each segment to hexadecimal and combine them, it becomes $C0A80101$, which only takes 8 characters.
This way, we can reduce the space occupied by the database.

Input Format

A single line containing a valid IP address (four numbers not exceeding 255, separated by three dots).

Output Format

For each test case, output a single line containing the hexadecimal string in lowercase letters.

Sample

192.168.0.1
