Merge Two Sorted Lists - LeetCode

WebWe already know that two linked lists can be merged in O (n) time and O (1) space (For arrays, O (n) space is required). The idea is to pair up k lists and merge each pair in linear time using the O (1) space. After the first cycle, K/2 lists are left each of size 2×N. After the second cycle, K/4 lists are left each of size 4×N and so on. WebLevel up your coding skills and quickly land a job.
