  • Ans. Brute force

    In this approach, we'll try to consider each rectangle that can be formed using elements of the array.

Now we have a rectangle with coordinates (X1,Y1), (X1,Y2), (X2,Y1) and (X2,Y2).

    We'll find the sum of elements within this rectangle and compare it with MAXSUM. ...
