题意：前面给出N和N个数，中间一串字符串（分割用），后面给出M和M个询问，问第I小的数字是多少。

分析：水。。。直接sort一下，然后输出第I-1个就好（下标从0开始）。

代码：

#include<cstdio>
#include<cmath>
#include<cstring>
#include<queue>
#include<stack>
#include<cstdlib>
#include<string>
#include<vector>
#include<map>
#include<string>
#include<iostream>
#include<algorithm>
using namespace std;
#define INF 0x3f3f3f3f
typedef long long ll;
#define Max(a,b) (a>b)?a:b
#define lowbit(x) x&(-x)
int n,a[1000005];
int main()
{scanf("%d",&n);for(int i=0;i<n;i++){scanf("%d",&a[i]);}sort(a,a+n);char s[105];scanf("%s",s);int m;scanf("%d",&m);while(m--){scanf("%d",&n);printf("%d\n",a[n-1]);}
}
