What is the difference between submatrix and minor?

As nouns the difference between submatrix and minor is that submatrix is (mathematics) a matrix formed by selecting certain rows and columns from a larger matrix while minor is a person who is below the legal age of responsibility or accountability.

How do I find the sum of a matrix?

Adding matrices We can find the sum simply by adding the corresponding entries in matrices A and B.

How do you find the maximum sum of a submatrix?

Follow the steps below to solve the problem:

1. Initialize a variable, say maxSum as INT_MIN, to store the maximum subarray sum.
2. Create a matrix prefMatrix[N][M] that stores the prefix array sum of every row of the given matrix.

What is the order of the largest square submatrix?

The largest square submatrix is formed by cells (0, 2) , (3, 2) , (0, 5) , and (3, 5) . The brute-force solution is to consider every square submatrix and check if it is surrounded by all 1’s .

How to find the maximum length of a square submatrix?

Given a N x M matrix where N is the number of rows and M is the number of columns in the given matrix and an integer K. The task is to find the maximum length of a square submatrix having the sum of elements less than or equal to K or print 0 if no such square exits.

How to find a sub matrix with the given sum?

Recommended: Please try your approach on {IDE} first, before moving on to the solution. Approach: Dynamic programming can be used to solve this problem, Create an array dp [N + 1] [N + 1] where dp [i] [j] stores the sum of all the elements with row between 1 to i and column between 1 to j.

How to store the maximum sum in a matrix?

Initialize a variable, say maxSum as INT_MIN, to store the maximum subarray sum. Create a matrix prefMatrix [N] [M] that stores the prefix array sum of every row of the given matrix.

How to do Kadane’s maximum sum submatrix algorithm?

Fix starting and ending column of the required sub-matrix say start and end respectively. Now, iterate each row and add row sum from starting to ending column to sumSubmatrix and insert this in an array. After iterating each row, perform Kadane’s Algorithm on this newly created array.
