For each number maintain a set that tells you at these bits position the above property is satisfied for the number and then try to find the one that will help in setting the AND to the maximum value as we can modify only one number. Think about binary representation of numbers, here point to note is the bit positions such that all the numbers have 1 at that position except 1 number that has a 0.Such bit positions can be changed to have all 1 by adding pow(2,i) (where i is the bit position) to that number which currently has a 0 at that location , this will increase the overall AND.
