首先第一种方法 两个单个节点还有进位相加实现如下: 1/**2* Definition for singly-linked list.3* public class ListNode {4* int val;5* ListNode next;6* ListNode(int x) { val = x; }7* }8*/9publicclassSolution {10publicListNode addTwoNumbers(ListNode l1, ListNode l2) {11if(l1==null&&...
LinkedList<Integer> list3 =newLinkedList<Integer>();intsum = 0;while(!list1.isEmpty() || !list2.isEmpty() || sum != 0) {inttempsum =sum;if(!list1.isEmpty()) { tempsum+=list1.poll(); }if(!list2.isEmpty()) { tempsum+=list2.poll(); } list3.addFirst(tempsum% 10); ...
总之,虽然list和linked list都是用于储存集合的元素,但是list是储存在连续的内存位置,可以用indices获取,但是linked list是储存在不同的结点位置,需要用结点之间的reference(指针)获取。 两数相加(addTwoNumbers) 两数之和是linked list中常见的问题之一,经常用于检测coder是否理解linked list和对linked list的操作。
