Failed test case

hello @vashishthkuntal.gajjar2019

i think u have misunderstood the question .

In the question u will be given two number a and b .

now you need to pick two numbers from the range [a…b] (say u picked x1 and x2)
such that their xor ( x1 ^ x2 ) is maximum.

but in that how will I take the input?
