sort进行排序,然后输出第k大的元素即可

#include<iostream>
#include<bits/stdc++.h>
#include<cstdio>

using namespace std;

int n, k;
int arr[10005];

int main()
{
    scanf("%d %d", &n, &k);
    for (int i = 0; i < n; i++){
        scanf("%d", &arr[i]);
    }
    sort(arr, arr+n);
    printf("%d", arr[n-k]);
    return 0;
}
