Maximum sum square submatrix. The maximum obtained sum is the answer.
Maximum sum square submatrix. Otherwise, we calculate the possible side length of a square ending at this cell by finding the minimum square side lengths from the right Jul 29, 2022 · Hey guys, In this video, We're going to solve the Maximum Sum SubMatrix Problem using Kadane's Algorithm. The goal is to find the maximum sum of all possible square submatrices of a specified size within the matrix. We run two nested loops, where the outer loop runs from 0 to n - k, and marks the row, while the inner row runs from 0 to n - k and marks the current column. Jul 23, 2025 · The idea is to generate all possible submatrices of order k * k, and find sum of its elements. So, Learn the Curated Stuff and also show Jul 28, 2025 · Now, we can apply Kadane’s algorithm on this temp [] array to find the maximum subarray sum, which corresponds to a rectangular submatrix with the maximum sum between columns left and right. int Can you solve this real interview question? Maximum Matrix Sum - You are given an n x n integer matrix. You can do the following operation any number of times: * Choose any two adjacent elements of matrix and multiply each of them by -1. Let's start with a brute force approach for finding the max contiguous subsequence and then consider optimizing it to get Kadane's algorithm. Problem Description: The task is to Can you solve this real interview question? Number of Submatrices That Sum to Target - Given a matrix and a target, return the number of non-empty submatrices that sum to target. 8K subscribers Subscribed Description Hi Guys, This Channel aims to provide with Curated Education to Students who want to grow, improve, learn and do something Big in their life. A submatrix x1, y1, x2, y2 is the set of all cells matrix [x] [y] with x1 <= x <= x2 and y1 <= y <= y2. This problem challenges us to find the submatrix with the maximum sum wi Coins of Geekland gfg Problem of the day | Maximum Sum Square SubMatrix | Dynamic Programming |Adobe Code with Alisha 30. Sep 18, 2025 · Given an `N × N` matrix, find the maximum sum submatrix present in it. cod Jul 12, 2025 · Find the middle index (say mid). If there is one row only or one column only, then this is equivalent to finding a maximum sub-array. Aug 24, 2024 · In this video, we tackle the Maximum Sum Square Submatrix problem from InterviewBit. Jul 26, 2025 · Try it on GfG Practice Naive Approach: The simplest approach is to generate all possible submatrices from the given matrix and calculate their sum. For example, the maximum sum submatrix is highlighted in green in the following matrices. Finally, print the maximum sum obtained. First we set the start and end of the rows which will form the topX and bottomX co-ordinates of the sub-array. The maximum obtained sum is the answer. For each cell, if its value is 0, we return 0 since it cannot contribute to a square. Apr 3, 2022 · Do Like Comment Share and Subscribe ️ ️📣 Day 7 : #goProWithBroCoders ️ Maximum Sum Square Sub-Matrix : https://www. Else Update the upper limit as mid - 1 to find the maximum sum with size less than mid. . Your goal is to maximize the summation of the matrix's elements. Sep 18, 2025 · Given an `M × N` matrix, calculate the maximum sum submatrix of size `k × k` in it in `O (M × N)` time. If the sum of elements of all possible square matrix of size mid is less than or equals to K, then update the lower limit as mid + 1 to find the maximum sum with size greater than mid. For example, consider the following `5 × 5` matrix. Problem Description Given a 2D integer matrix A of size N x N find a B x B submatrix where B<= N and B>= 1, such that sum of all the elements in submatrix is maximum. Below is the implementation of the above approach: Maximal Square - Given an m x n binary matrix filled with 0's and 1's, find the largest square containing only 1's and return its area. Given a $n\times m$ matrix $A$ of integers, find a sub-matrix whose sum is maximal. Return the maximum Oct 16, 2024 · This issue has been addressed by providing a solution to the problem of finding the submatrix with the maximum sum in a given 2D matrix of size N x N. Jan 16, 2024 · Instead of calculating sum for each submatrix of size B x B one by one, we can use a different strategy. Maximum Sum Square SubMatrix | Problem Description Given a 2D integer matrix A of size N x N find a B x B submatrix where B<= N and B>= 1, such that sum of all the elements in submatrix is maximum. Kadane's algorithm is a way to find a contiguous subsequence with maximum sum. 📍Join my paid Java DSA course here: https://www. Jul 23, 2025 · Using Recursion - O (3^ (n+m)) Time and O (n+m) Space The idea is to recursively determine the side length of the largest square sub-matrix with all 1s at each cell. Two elements are considered adjacent if and only if they share a border. yunnbm dyikxxov r7rbmk 2tnp too0oj0f q9ta cisk 7ej r1lcf 4f
