http://codeforces.com/problemset/problem/669/D 题意:n个数1~N围成一个圈.q个操作包括操作1:输入x, 所有数右移x.操作2:1,2位置上的数(swap(a[1], a[2])交换:3,4交换.... 题解:观察,发现所有奇数行为都是一样的,偶数同理,(对于操作1 两者相同,对于操作2 奇数位++,偶数位上--: 模拟1,2,即可,然后依次输出其它数字即可.(看清 ac代码: #define _CRT_SECURE_NO_WARNINGS #in…

题目链接: Codeforces 669D Little Artem and Dance 题目描述: 给一个从1到n的连续序列,有两种操作: 1:序列整体向后移动x个位置, 2:序列中相邻的奇偶位置互换. 问:q次操作后,输出改变后的序列? 解题思路: 刚开始只看了第一组样例,发现相邻的奇偶位一直在一起,于是乎就开始writing code,写完后发现并不是正解!!!!就去推了一下第三个样例,总是这组实例通过,那组实例卡死,,,,,,,最后终于成功的Mengbility.今天突然想起来,其实整体…

模拟. 每个奇数走的步长都是一样的,每个偶数走的步长也是一样的. 记$num1$表示奇数走的步数,$num2$表示偶数走的步数.每次操作更新一下$num1$,$num2$.最后输出. #pragma comment(linker, "/STACK:1024000000,1024000000") #include<cstdio> #include<cstring> #include<cmath> #include<algorithm> #i…

找每个数的约数(暴力就够了...1~x^0.5)....看这约数的倍数最后是哪个数...若距离大于了y..统计++...然后将这个约数的最后倍数赋值为当前位置...好叼的想法题.... Program: #include<iostream> #include<stack> #include<queue> #include<stdio.h> #include<algorithm> #include<string.h> #include&…
