Solution: Kth Smallest Number in M Sorted Lists
Explore how to find the kth smallest element from multiple sorted lists by implementing the k-way merge algorithm. This lesson helps you understand and apply min-heap structures to efficiently merge sorted lists while analyzing time and space complexities.
Statement
Given a list, lists, containing k, find the
Even if some values appear multiple times across the lists, each occurrence is treated as a unique element when determining the
If k exceeds the total number of elements across all lists, return the largest element among them. If the lists are empty, return 0.
Constraints:
-
lists[i].length -
lists[i][j]
