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 1:Input:l1=[1,2,4],l2=[1,3,4]Output:[1,1,2,3,4,4] Example 2:Input:l1=[],l2=[]Output:[] Example 3:Input:l1=[],l2=[0...
Merge two sorted linked lists and return it as a new list. The new list should be made by splicing together the nodes of the first two lists. Example: Input: 1->2->4, 1->3->4 Output: 1->1->2->3->4->4 翻译: 合并两个有序链表并返回一个新的链表,新链表必须由前两个链表拼接...
