题目传送门 /* 题意:n个数字转盘,刚开始每个转盘指向一个数字(0~n-1,逆时针排序),然后每一次转动,奇数的+1,偶数的-1,问多少次使第i个数字转盘指向i-1 构造:先求出使第1个指向0要多少步,按照这个次数之后的能否满足要求 题目读的好累:( */ #include <cstdio> #include <iostream> #include <algorithm> #include <cstring> #include <cmath>…

题目链接 可以发现 十进制4 对应 二进制100 十进制16 对应 二进制10000 十进制64 对应 二进制1000000 可以发现每多两个零,4的次幂就增加1. 用string读入题目给定的二进制数字,求出其长len,当len为奇数时,第一位为1,后面的位数如果都为0,则输出len,如果有一个不为0,则输出len+1: 当len为偶数时,则输出len.(之所以这样输出是因为题目给定4的次幂是从0开始的) #include<iostream> #include<string> #…

题目链接:http://codeforces.com/problemset/problem/556/B 题目意思:给出 n 个齿轮,每个齿轮有 n 个 teeth,逆时针排列,编号为0 ~ n-1.每按一次 button,每个齿轮都会有且仅有一个活动的tooth,对于偶数编号的齿轮,它下一个活动tooth是紧挨着当前tooth的逆时针方向的那个:而奇数编号的齿轮,下一个活动tooth是顺时针的那个.给出每个齿轮的活动tooth,问通过按下有限次的button,问能不能得到一个0,1,...,n-…
