代码如下

#include<bits/stdc++.h>
using namespace std;
int arr1[20005],arr2[20005];
int main(){
    int n,m;
    cin>>n>>m;
    for(int i=1;i<=n;i++){
        cin>>arr1[i];
    }
    for(int i=1;i<=m;i++){
        cin>>arr2[i];
    }
    sort(arr1+1,arr1+n+1);
    sort(arr2+1,arr2+n+1);
    int b=1,sum=0;
    for(int i=1;i<=n;i++){
        while(arr1[i]>arr2[b]){
            b++;
            if(b>m){
                cout<<"you died!";
                return 0;
            }
        }
        sum+=arr1[i];
    }
    cout<<sum;
    return 0;
}
