Solution: The K Weakest Rows in a Matrix

Explore how to determine the k weakest rows in a binary matrix by using a modified binary search to count soldiers in each row and a max-heap to track the weakest rows. This lesson helps you efficiently combine search techniques and data structures, improving your ability to solve matrix-related coding interview problems with optimal complexity.
