Hey Shubham, this is a basic strings problem, you have two inputs of equal length, and output for each bit is 1 if a[i]!=b[i] else 0.
See the length constraint (which is 100) so this problem can’t be done using even long long (64 bit)! Yes its a kind of XOR problem only done using strings

Ok, got it. Thank you
