真的自己写的！

#include<iostream>
using namespace std;

    cin >> n >> l >> r;
    char sign[n];
    int number[n];
    for(int i = 0;i < n;i++) cin >> sign[i] >> number[i];
    int q;
    cin >> q;
    while(q--){
        int x;
        cin >> x;
        long result = x;
        for(int i = 0;i < n;i++){
            if(sign[i] == '+') result += number[i];
            else if(sign[i] == '-') result -= number[i];
            else if(sign[i] == '*') result *= number[i];
            else if(sign[i] == '@') result += number[i] * x;

            if(result > r)result = r;
            else if(result < l)result = l;
        }
        cout << result << endl;
    }
    
    return 0;
