Solution: Count Negative Numbers in a Sorted Matrix

Understand how to efficiently count negative numbers in a non-increasing sorted matrix by scanning from right to left across rows. Learn the algorithm that reduces search operations using prior row insights, resulting in a linear time complexity. This lesson helps you apply matrix traversal techniques to solve practical coding interview problems.

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. ...
