WebA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. WebWe use a Dynamic Programming approach to solve this in O (N^3) For example if the N X N matrix is : and the value of k=4 The different sub matrices which have sum divisible by k (4 in this case)are: a). A sub matrix with sum=0 b). A sub matrix with sum=4 c). A sum matrix with sum=8 d). A sub matrix with sum=8 e). A sub matrix with sum=-4

WebSince all elements are nonnegative, the only way the submatrix sum equals 0 is if all elements are 0. The optimal solution for that problem is O (nm^2) or O (mn^2) 7 Reply … Web25 Nov 2024 · Subarrays are the contiguous part of an array. For example, we consider an array [5, 6, 7, 8], then there are ten non-empty subarrays like (5), (6), (7), (8), (5, 6), (6,7), (7,8), (5,6,7), (6,7,8) and (5,6,7,8). In this guide, we will explain every possible information to find the number of subarrays with odd sums in C++.

Find the largest submatrix consisting of only zeros (a submatrix is a rectangular area of the matrix). Algorithm Elements of the matrix will be a [i] [j], where i = 0...n - 1, j = 0... m - 1. For simplicity, we will consider all non-zero elements equal to 1.
