A Ducci sequence is a sequence of n-tuples of integers. Given an n-tuple of integers (a1, a2, · · · , an), the next n-tuple in the sequence is formed by taking the absolute differences of neighboring integers: (a1, a2, · · · , an) → (|a1 − a2|, |a2 −…

Ducci Sequence Description   A Ducci sequence is a sequence of n-tuples of integers. Given an n-tuple of integers (a1, a2, ... , an), the next n-tuple in the sequence is formed by taking the absolute differences of neighboring integers: ( a1, a2, ...…

题意: 对于一个n元组(a0,a1,...),一次变换后变成(|a0-a1|,|a1-a2|,...) 问1000次变换以内是否存在循环. 思路: 模拟,map判重 代码: #include <cstdio> #include <cstring> #include <map> #include <cmath> #include <algorithm> using namespace std; struct Node{ ]; int n; void…

想麻烦了.这题真的那么水啊..直接暴力模拟,1000次(看了网上的200次就能A)后判断是否全为0,否则就是LOOP: #include <iostream> #include <sstream> #include <cstdio> #include <cstring> #include <cmath> #include <string> #include <vector> #include <set> #in…

水题,算出每次的结果,比较是否全0,循环1000次还不是全0则LOOP AC代码: #include <iostream> #include <cstdio> #include <cstdlib> #include <cctype> #include <cstring> #include <string> #include <sstream> #include <vector> #include <set…

题目 题目     分析 真的快疯了,中午交了一题WA了好久,最后发现最后一个数据不能加\n,于是这次学乖了,最后一组不输出\n,于是WA了好几发,最后从Udebug发现最后一组是要输出的!!!     代码 #include <cstdio> #include <cmath> #include <algorithm> using namespace std; int n,a[25]; bool s() { for(int i=0;i<n;i++) if(a[i]…

题目链接 题意:一张纸,每次从右往左对折.折好以后打开,让每个折痕都自然的呈90度.输出形状. 思路:模拟折……每次折想象成把一张纸分成了正面在下的一张和反面在上的一张.维护左边和方向,然后输出.细节有点多. 代码: #include <cstdio> #include <cstdlib> #include <cstring> #include <algorithm> using namespace std; #define N (1<<13)+…
