C - Boxes in a Line 数组模拟链表

You have n boxes in a line on the table numbered 1 . . . n from left to right. Your task is to simulate 4 kinds of commands: • 1 X Y : move box X to the left to Y (ignore this if X is already the left of Y ) • 2 X Y : move box X to the right to Y (ig…

UVa12657 - Boxes in a Line(数组模拟链表)

题目大意你有一行盒子,从左到右依次编号为1, 2, 3,…, n.你可以执行四种指令: 1 X Y表示把盒子X移动到盒子Y左边(如果X已经在Y的左边则忽略此指令).2 X Y表示把盒子X移动到盒子Y右边(如果X已经在Y的右边则忽略此指令).3 X Y表示交换盒子X和Y的位置.4 表示反转整条链. 盒子个数n和指令条数m(1<=n,m<=100,000) 题解用数组来模拟链表操作,对于每个节点设置一个前驱和后继. 1操作是把x的前驱节点和x的后继节点连接,y节点的前驱和x节点连接,x节点和y…

PAT 甲级 1052 Linked List Sorting (25 分)（数组模拟链表，没注意到不一定所有节点都在链表里）

1052 Linked List Sorting (25 分) A linked list consists of a series of structures, which are not necessarily adjacent in memory. We assume that each structure contains an integer key and a Next pointer to the next structure. Now given a linked list,…
