Solution: Count Negative Numbers in a Sorted Matrix

Explore the method for counting negative numbers in a matrix where each row and column is sorted in non-increasing order. Learn to optimize the search by starting from the rightmost column and moving left, updating the starting point for each row to avoid repeated work. This lesson helps you implement an efficient O(m+n) time algorithm with constant space, enhancing your skills in matrix traversal and problem-solving under common coding interview constraints.
