Lintcode36 Reverse Linked List II solution 题解

【题目描述】

Reverse a linked list from position m to n.

Notice:Given m, n satisfy the following condition: 1 ≤ m ≤ n ≤ length of list.

翻转链表中第m个节点到第n个节点的部分

注意:m，n满足1 ≤ m ≤ n ≤ 链表长度

【题目解析】

反转整个链表的变种，指定了起点和终点。由于m=1时会变动头节点，所以加入一个dummy头节点

1. 找到原链表中第m-1个节点start：反转后的部分将接回改节点后。

2. 将从p = start->next开始，长度为L = n-m+1的部分链表反转。

3. 最后接回
