Statement

Professor Xavier wants to start a season of team programming olympiads at a school for gifted mutants. Each team has been given a login, but since most mutants at the school are still children, many students have misremembered their login.

A valid login is a string made of two parts. The first part is the two letters io, and the second part is a string of digits. So io182865 is a valid login, while ind3038 is not.

Each student wants to know whether their login is valid. To avoid checking each query by hand, the Professor asks you to write a program that determines whether a login is valid.

Input

The only line of the input contains the string $s$ ( $1 \le |s| \le 10$ ), the participant's login, made of lowercase Latin letters and digits.

Output

Print Correct if the login is valid for this contest, otherwise print Incorrect.
