Count Total Number (or Total Area) of Square Submatrices

Problem: Count Square Regions Containing Only Ones You are given a binary m x n matrix named matrix. Determine the overall count of square submatrices made entirely of 1s, including every possible square side length. Input m n m lines, each containing n binary entries (0 or 1), written either with spaces or as consecutive characters. Output One integer representing the number of all-ones square submatrices. Constraints 1 <= m, n <= 1000 Example Input: Output: There are six…
