Description

Boudreaux and Thibodeaux are on the road again . . . "Boudreaux, we have to get this shipment of mudbugs to Baton Rouge by tonight!" "Don't worry, Thibodeaux, I already checked ahead. There are three underpasses and our 18-wheeler will fit through all of them, so just keep that motor running!" "We're not going to make it, I say!" So, which is it: will there be a very messy accident on Interstate 10, or is Thibodeaux just letting the sound of his own wheels drive him crazy?

Input

Input to this problem will consist of a single data set. The data set will be formatted according to the following description. The data set will consist of a single line containing 3 numbers, separated by single spaces. Each number represents the height of a single underpass in inches. Each number will be between 0 and 300 inclusive.

Output

There will be exactly one line of output. This line will be: NO CRASH if the height of the 18-wheeler is less than the height of each of the underpasses, or: CRASH X otherwise, where X is the height of the first underpass in the data set that the 18-wheeler is unable to go under (which means its height is less than or equal to the height of the 18-wheeler). The height of the 18-wheeler is 168 inches.

Sample Input

180 160 170

Sample Output

CRASH 160
