Example
input n=3,k=3
i
T
he results of the comparisons are below:


a b   and or xor
1 2   0   3  3
1 3   1   3  2
2 3   2   3  1
For the and comparison, the maximum is 2 
For the or comparison, none of the values is less than k, so the maximum is 0.
For the xor comparison, the maximum value less than  is k . The function should print: 1

2
0
2
