反转从位置 m 到 n 的链表.用一次遍历在原地完成反转.例如:给定 1->2->3->4->5->NULL, m = 2 和 n = 4,返回 1->4->3->2->5->NULL.注意:给定 m,n 满足以下条件:1 ≤ m ≤ n ≤ 列表长度.详见:https://leetcode.com/problems/reverse-linked-list-ii/description/ Java实现: /** * Definition for
Problem Statement You are given two integer sequences, each of length N: a1,…,aN and b1,…,bN. There are N2 ways to choose two integers i and j such that 1≤i,j≤N. For each of these N2 pairs, we will compute ai+bj and write it on a sheet of paper. That
