Solution: Kth Smallest Element in a Sorted Matrix
Understand how to use the k-way merge pattern with a min-heap to efficiently find the kth smallest element in a sorted n by n matrix. This lesson explains the algorithm that treats each row as a sorted list and details how to merge them, while analyzing the time and space complexities.

Statement
Find the smallest element in an matrix, where each row and column of the matrix is sorted in ascending order.
Although there can be repeating values in the matrix, each element is considered unique and, therefore, contributes to calculating the smallest element.
