Equations 题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=2086 ——每天在线,欢迎留言谈论. 题目大意: 有如下方程:Ai = (Ai-1 + Ai+1)/2 - Ci (i = 1, 2, 3, .... n). 若给出A0, An+1, 和 C1, C2, .....Cn. 求 A1 . 思路: 多写几个例子,找规律推导(抄的). 感想: 老啦,老啦,不行了. Java AC代码: import java.util.Scanner;…

HDU 1029 题目大意:给定数字n(n <= 999999 且n为奇数 )以及n个数,找出至少出现(n+1)/2次的数 解题思路:n个数遍历过去,可以用一个map(也可以用数组)记录每个数出现的次数, 若次数一旦达到(n+1)/2,即输出a[i] 注意能出现(n+1)/2次数的最多只有一个 /* HDU 1029 *Ignatius and the Princess IV --- dp */ #include <cstdio> #include <cstring> #in…
