Solution: The K Weakest Rows in a Matrix

Explore an algorithm to find the k weakest rows in a matrix where soldiers are represented by ones and civilians by zeros. Learn to apply binary search to count soldiers per row efficiently and use a max-heap to track and return the weakest rows in order, balancing 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  ...
