• 题目大意:给定n个数字,输出其中出现次数超过n/2的数字

#include <algorithm>
#include <cstdio>
using namespace std;
const int maxn = 1E6 + 10;
int a[maxn];
int main(){
        int n;
        while(~scanf("%d",&n)){
                for(int i = 1;i <= n ;++i){
                        scanf("%d",&a[i]);
                }
                sort(a,a+n);
                a[0] = a[1] - 1;
                int i,cnt = 0;
                for(i = 1;i <= n ;++i){
                       if(a[i] == a[i - 1])     ++cnt;
                        else cnt = 1;
                        if(cnt >= (n + 1)/2)    break;
                }
                printf("%d\n",a[i]);
        }
        return 0;
}
