Solution: The K Weakest Rows in a Matrix

Explore how to find the k weakest rows in a binary matrix by combining modified binary search with a max-heap. Understand how the algorithm counts soldiers in each row and prioritizes rows to return the weakest ones efficiently, along with analyzing its 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  ...
