SP17309 OPBIT - Operation Bits

Operation bits - A new operation conducted by the secret team currently working on a project on security enhancement. Mr.Abay, the team head, has found a new pattern on the perfect squares. This can be used as a outer cover for his project as its securing power is low. So he assign you this problem to find the key based on the given conditions: "An two adjacent perfect squares have their absolute difference as an odd number except when a and b are equal. Your task is to find the key which is deined as: key(a,b) where a and b are perfect squares is ( ( AND( absolute difference betwen every adjacent perfect squares in \[a,b\]) ) AND ( XOR( absolute difference betwen every adjacent perfect squares in \[a,b\]) ) )" Find the key for the given inputs :)

The input begins with a number T (1

For each test case print the corresponding key
