Solution: The K Weakest Rows in a Matrix

Explore how to solve the problem of finding the k weakest rows in a binary matrix by combining modified binary search with a max-heap. Learn to efficiently count soldiers using binary search on sorted rows and manage the weakest rows with a heap. Understand key concepts like tie-breaking by row index and analyze the algorithm's time and space complexity.

Statement

You are given an m×nm \times n binary matrix of 11’s (representing soldiers) and 00’s (representing civilians). The soldiers are positioned in front of the civilians, i.e., all the  ...
