每日一练-leetcode

剑指 Offer 52. 两个链表的第一个公共节点

输入两个链表，找出它们的第一个公共节点。

此题与上次咱们做的思路是一样的可见前两次博客

/**
 * Definition for singly-linked list.
 * public class ListNode {
 *     int val;
 *     ListNode next;
 *     ListNode(int x) {
 *         val = x;
 *         next = null;
 *     }
 * }
 */
public class Solution {
    public ListNode getIntersectionNode(ListNode headA, ListNode headB) {
        ListNode pre,cur;
        pre = headA;
        cur = headB;
        while(pre != cur){
        pre = pre == null?headB:pre.next;
        cur = cur == null?headA:cur.next;
        }
        return pre;
    }
}
