题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=2010 题目大意:给你段连续的数,把满足条件(数字 每一位的3 == 该数字)的数输出,就是水仙花数 解题思路: 很水,考察取余数(%)的基本运用 代码: #include<iostream> #include<cmath> //#include<cstdio> #include<iomanip> //#include<algorithm> using…

http://acm.hdu.edu.cn/showproblem.php?pid=2010 春天是鲜花的季节,水仙花就是其中最迷人的代表,数学上有个水仙花数,他是这样定义的:“水仙花数”是指一个三位数,它的各位数字的立方和等于其本身,比如:153=1^3+5^3+3^3.现在要求输出所有在m和n范围内的水仙花数. Solution:水仙花数又称阿姆斯特朗数,没有直接规律,只能暴力求解. 有限数列,打表算了(懒写暴力) 使用在线算法打大表: 1:  1, 2, 3, 4, 5, 6, 7, 8,…

HDU - 1260 现在有n个人要买电影票,如果知道每个人单独买票花费的时间, 还有和前一个人一起买花费的时间,问最少花多长时间可以全部买完票. 直接dp就行,注意下输出和初始化 每次从dp[i-1]和dp[i-2]里面选一个就好 #include <bits/stdc++.h> #define ll long long #define IO ios::sync_with_stdio(false);cin.tie(0);cout.tie(0) #define pp pair<int,i…

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 (…
