这段代码为什么会报语法错误：int miceAndCheese(vector<int>& reward1, vector<int>& reward2, int k) { vector<pair<int, int>>v; for(int i = 0; i < reward1.size(); i++) { v.push_back(make_pair(reward1[i], reward2[i])); } sort(v.begin(), v.end(), greater<int>()); int ans = 0; for(int i = 0; i < v.size(); i++) cout << v[i].first << " " << v[i].second << endl; return ans; } };

这段代码会报语法错误是因为有一个多余的 "}; "在代码的末尾，应该将它删除。代码的正确形式如下：

int miceAndCheese(vector<int>& reward1, vector<int>& reward2, int k) {         
    vector<pair<int, int>>v;         
    for(int i = 0; i < reward1.size(); i++) {             
        v.push_back(make_pair(reward1[i], reward2[i]));         
    }         
    sort(v.begin(), v.end(), greater<int>());         
    int ans = 0;         
    for(int i = 0; i < v.size(); i++) cout << v[i].first << " " << v[i].second << endl;         
    return ans;     
}
