http://acm.hdu.edu.cn/showproblem.php?pid=4731 就做了两道...也就这题还能发博客了...虽然也是水题 先暴力DFS打表找规律...发现4个一组循环节...尾部特殊判断....然后构造一下... #include <cstdio> #include <string> #include <cstdlib> #include <cstring> #include <iostream> #include &…

题目 大意: 求二进制的a加到b的进位数. 思路: 列出前几个2进制,找规律模拟. #include <stdio.h> #include <iostream> #include <algorithm> #include <string.h> #include <math.h> #include <stack> #include <vector> using namespace std; int main() { int…

题意: 有n堆石子,alice先取,每次可以选择拿走一堆石子中的1~x(该堆石子总数) ,也可以选择将这堆石子分成任意的两堆.alice与bob轮流取,取走最后一个石子的人胜利. 思路: 因为数的范围比较大,所以最好通过SG打表的结果找出规律在解. sg(4k+1)=4k+1;sg(4k+2)=4k+2;sg(4k+3)=4k+4; sg(4k)=4k-1; 1 2 4 3 5 6 8 7 Sample Input232 2 323 3 Sample OutputAliceBob SG打表找规律…

题目 最近比赛的题目好多签到题都是找规律的考验智商的题目啊,,,我怎么越来越笨了,,,, 通过列举,可以发现规律: 从左往右按位扫这个数: 当数的长度大于1时: 当首位大于3时,答案就是4*4*4*……*4*3(即pow(4,后面的长度-1)*3): 否则,则是 首位的数字*4*4*4*……*4*3: 当数的长度为1时,并且之前的(即其他的)都没有进位,则直接判断一下ans要加多少个: #include<stdio.h> #include<string.h> #include<…
