题目大意是找出数组中出现次数超过一半的数. 基本思想:每遇到两个不同的数就消掉,设一个计数器就行了.   存出现次数最大的那个数的出现次数. 当下一个数与当前的数不同时,计数器减一,相同,则加一. 实现代码: #include <iostream> #include <stdio.h> using namespace std; int main() { int n,x,m_max,cnt; // while(cin>>n) while(scanf("%d&qu…

Ignatius and the Princess IV  先搬中文 Descriptions:   给你n个数字,你需要找出出现至少(n+1)/2次的数字 现在需要你找出这个数字是多少? Input 本题包含多组数据,请处理到EOF: 每组数据包含两行. 第一行一个数字N(1<=N<=999999) ,保证N为奇数. 第二行为N个用空格隔开的整数. Output 对于每组数据,输出一行,表示要求找到的那个数 Sample Input 5 1 3 2 3 3 11 1 1 1 1 1 5 5…

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…
