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. Understand a step-by-step algorithm that starts from the right-most elements, moves leftward, and uses previously found indices to optimize the search across rows. This lesson highlights the method's time complexity of O(m+n) and constant space usage, helping you apply this strategy to similar matrix problems in coding interviews.
