Maximum Sum Rectangle in a 2D Matrix DP Love Babbar DSA Sheet GFG
A 2D matrix is a grid of numbers. The Maximum Sum Rectangle problem requires us to find a rectangle within this grid such that the sum of the numbers within the rectangle is as high as possible. This rectangle can be as small as 1x1, and as large as the entire matrix. Solving the Problem. Firstly, let's create our 2D matrix.

Maximum sum Rectangle Try It! The Naive Solution for this problem is to check every possible rectangle in the given 2D array. This solution requires 6 nested loops - 4 for start and end coordinate of the 2 axis O (n4) and 2 for the summation of the sub-matrix O (n2). Below is the implementation of the above approach: C++ Java Python3 C# Javascript

Question Video Finding the Maximum Area of a Rectangle given the Sum
Maximum sum rectangle is a rectangle with the maximum value for the sum of integers present within its boundary, considering all the rectangles that can be formed from the elements of that matrix. For Example Consider following matrix: The rectangle (1,1) to (3,3) is the rectangle with the maximum sum, i.e. 29. Input Format
Massive Algorithms Dynamic Programming Set 27 (Maximum sum rectangle
When values in the matrix are all positive the answer is pretty straight forward, the maximum sum rectangle is the matrix itself. We use dynamic programming to reduce the brute force time complexity to O (N^3). The idea is to fix the left and right columns one by one and find the maximum sum contiguous rows for every left and right column pair.

Maximum sum rectangle in a 2D matrix Solution Basic Solution. The basic approach is to iterate over all rectangles. Since we are dealing with a 2-D matrix we require 4 loops to iterate and 2 loops to find sum. Thus the time complexity of this approach is O((r^3)*(c^3)).
