Solution: Count Negative Numbers in a Sorted Matrix

Explore an optimized approach to count all negative numbers in a matrix sorted in non-increasing order by rows and columns. Learn to traverse the matrix efficiently by leveraging its sorted properties, resulting in a time complexity of O(m+n) and constant space usage. This lesson helps you implement and understand the solution to solve matrix-based coding interview problems with improved performance.

Statement

Given a matrix grid of size m  nm \ * \ n, where each row and column is sorted in non-increasing order, find and return the total count of negative numbers in the matrix. ...
