Rumor has it that sabotages on spaceships started happening more often. In order to solve this problem, the transporting company developed a scanning device that detects impostors among crew members.

The device collects information about all people on the spaceship and keeps it in a convenient manner. The information is stored in a single string S that consists of words “Crewmate” and “Impostor” not separated by spaces. The only thing left is to implement a module that would analyze this string and tell everybody how many impostors are there on the spaceship. And the crew is to decide what happens next.

The first line contains the string S (8 ≤ |S| ≤ 96, where |S| is the string’s length).

If there are impostors on the ship, output a single line “There is x Impostor among us”, where x is the number of impostors. Otherwise output a single line “Clear”.
