Farid likes hip-hop and once he saw a message in Twitter from Lil Pump:
Farid wants to have program to check if Lil Pump is right for some pair of given integers. Help him to write it.
Input contains two integers a and b (0 ≤ a,b ≤ 109).
If Lil Pump is right for fiven numbers, print “ESSKEETIT”, otherwise print “NO”
