Solution: Count Negative Numbers in a Sorted Matrix

Explore how to efficiently count negative numbers in a matrix where each row and column is sorted in non-increasing order. Learn to leverage the matrix's sorted properties to reduce traversal steps and optimize your solution with O(m+n) time complexity and O(1) space usage.

We'll cover the following...

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. ...
