答案

#include <iostream> using namespace std; int main() { int a, b; cin >> a >> b; int groups = b / (3 * a); // 可以购买的完整组数 int free_chicken = groups; // 免费获得的鸡腿数 int total_paid = 3 * a * groups; // 已支付的金额 int remaining_money = b - total_paid; // 剩余的钱 int additional_chicken = remaining_money / a; // 用剩余的钱购买的鸡腿数 int total = 4 * groups + additional_chicken; // 总鸡腿数 cout << total << endl; return 0; }
