5) Merge k Sorted Lists You are given an array of x linked-lists lists, each linked-list is sorted in ascending order. Merge all the linked-lists into one sorted linked-list and return it. Example 1: Input: 1 ists =[11,4,5],[1,3,4],[2,6]} Output: [1,1,2,3,4,4,5,6] Zxplanation: The linked-1ists are: [. 145. 134, 26 merging them into one sorted list: 11234456 Example 2: Input: lists [1 output: [1. Example 3: Input: 11 sts =[[1] Output: [1) Constraints: - k= ists. length - 0
