$不会调啊！！！$

$代码：$

#include<bits/stdc++.h>
using namespace std;
#define int long long
const int N = 2e5+5;
int m, n, a[N], b[N];
signed cmp (int x, int y) {
	return x < y;}

	cin >> m >> n;int cntel=0, cntqs=0;
	for (int i = 1; i <= m; i++) {
		cin >> a[i];cntel+=a[i];
	}for (int i = 1; i <= n; i++) {
		cin >> b[i];cntqs+=b[i];
	}sort(a+1,a+m+1,cmp);sort(b+1,b+n+1,cmp);
	if (m>n)
	for (int i = 1; i <= m; i++) {
		if (a[i] <= b[j]){
            ans++;f+=b[j];b[j]=0;j++;
            if (ans==m)return cout << f, 0;
        }
	} 
	cout << "you died!" << endl;
 	return 0;
}
