In this post we will solve LeetCode 1504. Count Submatrices With All Ones problem using the Java programming language, the VSCode IDE on a Windows computer. My suggestion to you is that unless you have some special set of requirements, use the online IDE provided by LeetCode.
Given an m x n binary matrix mat, eturn the number of submatrices that have all ones. Constraints: o 1 <= m, n <= 150 o mat[i][j] is either 0 or 1. Related Topics: o Array * Dynamic Programming o Stack o Matrix o Monotonic Stack
In this problem we are provided a two dimensional matrix that only contains 1s and 0s. The dimensions are specified by `n` and `m`. Our mission if we wish to accept it, is to return the number of submatrices of 1s. Continue reading “LeetCode 1504. Count Submatrices With All Ones in Java”
