Each army fighting the world war Z is denoted with a word consisting any combination of 26 alphabets. An army is a match for his/her opponent if and only if his name is an anagram of his/her opponent. Your job as a programmer is to help find whether two randomly selected members are match for each other or not.

Eg: Silent is anagram to listen.)
