LeetCode: 21-Merge Two Sorted Lists 解題紀錄

Last Updated on 2021-01-31 by Clay

Merge two sorted linked lists and return it as a sorted list. The list should be made by splicing together the nodes of the first two lists.

Example:

Input: l1 = [1,2,4], l2 = [1,3,4]
Output: [1,1,2,3,4,4]

題目輸入兩個已經排序過的 Linked List，而我們要將其『合併』，並回傳同樣排序過的 Linked List。
