1040水题; These days, I am thinking about a question, how can I get a problem as easy as A+B? It is fairly difficulty to do such a thing. Of course, I got it after many waking nights.Give you some integers, your task is to sort these number ascending (…

题意:判断一些数里有最大因子的数 水题,省赛即将临近,高效的代码风格需要养成,为了简化代码,以后可能会更多的使用宏定义,但是通常也只是快速拿下第一道水题,涨自信.大部分的代码还是普通的形式,实际上能简化的部分也不太多 #include<iostream> #include<cstring> #include<cmath> #include<cstdio> using namespace std; #define for0n for(i=0;i<n;i+…

/* 对于只会弗洛伊德的我,迪杰斯特拉有点不是很理解,后来发现这主要用于单源最短路,稍稍明白了点,不过还是很菜,这里只是用了邻接矩阵 套模板,对于邻接表暂时还,,,没做题,后续再更新.现将这题贴上,应该是迪杰斯特拉最水的题没有之一.纯模板 找到距离起点最近的点,以此点为中间点进行更新,找到了在进行下一个点. */ 题目大意: 搬东西很累,想省力,给你几个点和点之间的距离:标准题型: #include<stdio.h> #include <iostream> #include<…

http://acm.hdu.edu.cn/showproblem.php?pid=5038 就是求个众数  这个范围小 所以一个数组存是否存在的状态即可了 可是这句话真恶心  If not all the value are the same but the frequencies of them are the same, there is no mode. 事实上应该是这个意思: 当频率最高的有多个的时候. 假设 全部的grade出现的频率都是相等的,那么是没有mode的 否则依照升序 当…
