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…

题目链接:http://codeforces.com/contest/1154/problem/E 题意:两个人轮流取最大值与旁边k个数,问最后这所有的数分别被谁给取走了 分析:看这道题一点思路都没有,想不到模拟链表也该能想到线段树的啊 大部分AC代码是模拟链表的,写起来也更快,但我线段树很不熟,线段树的代码也写一份吧 另外,以后要养成一种习惯,除了主函数定义int main里有int外,其他地方统一用ll了,不要自己给自己挖坑..... 线段树: 意识到是线段树后我建树部分就拿不准怎么做,事实…

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…

题目链接 题目描述 给定一个单链表 L1→L2→...→Ln-1→Ln,请编写程序将链表重新排列为 Ln→L1→Ln-1→L2→....例如:给定L为1→2→3→4→5→6,则输出应该为6→1→5→2→4→3. 输入格式: 每个输入包含1个测试用例.每个测试用例第1行给出第1个结点的地址和结点总个数,即正整数N (<= 105).结点的地址是5位非负整数,NULL地址用-1表示. 接下来有N行,每行格式为: Address Data Next 其中Address是结点地址:Data是该结点保存的…
