Maximize Bitwise AND of first element with complement of remaining elements for any permutation of given Array | Function to maximize the value for the given function and the array elements.
Vector array to maintain which bit is set for which integer in the given array by saving index of that integer.
Check if j - th bit is set for i - th integer.
Push the index of that integer in setBit [ j ].
Find the element having highest significant set bit unset in other elements.
Place that integer at 0 - th index.
Store the maximum AND value.
Return the answer.
