Web5 dec. 2024 · Merge K Sorted Lists We have dealt with a more specific case of this problem in the post LeetCode #21 - Merge Two Sorted Lists. Current problem is the generic case of the same problem. Problem Statement You are given an array of k linked-lists lists, each linked-list is sorted in ascending order. WebApproach: To get all possible ranges we first merge all ‘K’ lists into one single list and then traverse on all possible pairs. For each pair, we assume the first element of the pair as the starting of our range and the second element as the ending of our range (vice versa if the first element is greater than the second element).
