public ListNode mergeTwoLists(ListNode l1, ListNode l2) { if (l1 == null){ return l2; } else if (l2 == null){ return l1; } else if (l1.val < l2.val){ l1.next = mergeTwoLists(l1.next, l2); return l1; } else{ l2.next = mergeTwoLists(l1, l2.next); return l2; } }...
The method returns the mergedList at the end.Using the main() method, we demonstrate the use of mergeLists() by passing two lists of integers (numbers1 and numbers2) and two lists of strings (words1 and words2). We merge the elements of each pair of lists and print the merged lists...
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. 两个排好序的链表拼接,只要用两个指针遍历链表即可. 可以借助一个helper指针来进行开头的合并。如果有一个遍历完,则直接把另一个链表指针之后的部分全部接...
Java [leetcode 21]Merge Two Sorted Lists 题目描述: 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. 解题思路: 题目的意思是将两个有序链表合成一个有序链表。
