好久没写什么数论,同余之类的东西了. 昨天第一次用了剩余定理解题,今天上百度搜了一下hdu中国剩余定理.于是就发现了这个题目. 题目的意思很简单.就是告诉你n个m[i],和n个a[i].表示一个数对m[i]取模的值为a[i]. 乍一看以为这个题目可以用中国剩余定理,但是看仔细了吗?这里的mi并没有说是互素的哦. 肿么办?只能用安叔以前说的解同余方程的那种土方法了. 上代码:(我稍微改进了一下,根据题目的具体情况). #include <iostream> #include <cstdio…

<题目链接> 题目大意: 给你一些模数和余数,让你求出满足这些要求的最小的数的值. 解题分析: 中国剩余定理(模数不一定互质)模板题 #include<stdio.h> using namespace std; #define ll long long ll A[],B[];//B[i]为余数 ll dg,ans;//dg为A[i]的最小公倍数 ans 为最小解 void exgcd(ll a, ll b, ll &d, ll&x, ll &y) { ; y…

题意:Kiki 有 X 个硬币,已知 N 组这样的信息:X%x=Ai , X/x=Mi (x未知).问满足这些条件的最小的硬币数,也就是最小的正整数 X. 解法:转化一下题意就是 拓展欧几里德求解同余方程组了.我们可以得到 N 个方程:Mi*x+Ai=X.一些解释请看下面的代码. 1 #include<cstdio> 2 #include<cstdlib> 3 #include<cstring> 4 #include<iostream> 5 using na…
