Solution: The K Weakest Rows in a Matrix

Explore how to solve the problem of finding the k weakest rows within a binary matrix where soldiers, represented by 1s, precede civilians. This lesson teaches you to apply binary search to count soldiers efficiently and use a max-heap to track the weakest rows. By the end, you will understand managing time and space complexity in such problems and be able to implement a solution that handles sorted binary matrices effectively.

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  ...
