Rearrange an array to maximize sum of Bitwise AND of same | Function to implement recursive DP.
If i is equal to N.
If dp [ i ] [ mask ] is not equal to - 1.
Iterate over the array B [ ].
If current element is not yet selected.
Update dp [ i ] [ mask ].
Return dp [ i ] [ mask ].
Function to obtain maximum sum of Bitwise AND of same - indexed elements from the arrays A [ ] and B [ ].
Stores all dp - states.
Returns the maximum value returned by the function maximizeAnd ( ).
