#include <bits/stdc++.h>
using namespace std;

int main(){
    int n,m;
    cin>>n>>m;

        int l=0,r=n+1;
        while(l<r){
            int mid=(l+r)/2;
            if(a[mid]<=b[i])l=mid+1;
            else r=mid;
        }
        if(b[i]<=a[1])ans+=a[1]-b[i];
        else ans+=min(abs(a[l-1]-b[i]),abs(a[l]-b[i]));
    }
    cout<<ans;
    return 0;
}

恳求大佬帮忙看看

@QinYulang 楼上其实是对的(

#include <bits/stdc++.h>
using namespace std;
long long int a[100100],b[100100];
int main(){
    long long int n,m;
    cin>>n>>m;
    for(int i=1;i<=n;i++)cin>>a[i];
    for(int i=1;i<=m;i++)cin>>b[i];
    sort(a+1,a+n+1);
    long long int ans=0;
    for(int i=1;i<=m;i++){
        long long int l=0,r=n+1;
        while(l<r){
            long long int mid=(l+r)/2;
            if(a[mid]<=b[i])l=mid+1;
            else r=mid;
        }
        if(b[i]<=a[1])ans+=a[1]-b[i];
        else ans+=min(abs(a[l-1]-b[i]),abs(a[l]-b[i]));
    }
    cout<<ans;
    return 0;
}

为了方便,我全部改成 long long 了。没什么压力。看了一下题,数据规模完全限制在 long long 内了。
