GAH Policy

CodeChefOpen on judge ↗

You are given a string consisting of $3$ characters, $G$, $A$ and $H$, which are the initials of this contest name. A string is considered good if "Difference between the positions of the same character is divisible by 3." For example, GAHGAHGA, GA and H are good strings. But GAHA and AA are not good strings.   Note: GA is a good string because there are no positions which have the same colour
