@bitset_iTM 怎么卡

by bitset_iTM @ 2024-10-18 20:02:58

@E303 使用 cin 加速

ios :: sync_with_stdio(0); cin.tie(0); cout.tie(0);

code

#include<bits/stdc++.h>
using namespace std;
int a[5000005];
int main(){
    ios :: sync_with_stdio(0); cin.tie(0); cout.tie(0);
    register int n,k=0;
    cin>>n>>k;
    for(register int i=0;i<n;i++){
        cin>>a[i];
    }
    stable_sort(a,a+n);
    cout<<a[k]<<'\n';
}
