#173 Anti-Greek Debugging

Statement

Statement language

The Greek question mark U+037E and the semicolon U+003B look exactly the same, so they are hard to distinguish by eye. However, they are different Unicode characters.

Because of this, Kuong once used a Greek question mark instead of a semicolon while coding in C++, causing a compilation error. Since then, Kuong has hated Greek question marks.

You are given the Unicode code points of the characters that make up a piece of code. Determine whether the code contains a Greek question mark. Kuong is very good at coding and can easily find the cause of any other C++ compilation error, so you only need to check whether a Greek question mark exists.

Input

The input is given in the following format.

$N$ $S_1$ $S_2$ $\vdots$

$S_i$ is a string representing the Unicode code point of the $i$ -th character of the code.

Output

If the code contains a Greek question mark, print Greek Question Mark is not allowed.

Otherwise, print Good Code.

Constraints

$1 \le N \le 1\,000\,000$ .
$S_i$ is a string of length $6$ consisting of followed by four hexadecimal digits from to .
