Please describe the bug below and include any steps to reproduce the bug or screenshots if possible.

Although the Encode and Decode String problem solution is correct but there is some issue in the compiler

public:

    string encode(vector<string>& strs) {
        string ans = "";

        for(string &s: strs){
            ans += to_string(s.size()) + "$" + s;
        }
        return ans;
    }

    vector<string> decode(string s) {
        vector<string> ans;
        int i = 0, n = s.size();

        while(i < n){
            int j = i;

            while(j < n && s[j] != '$'){
                j++;
            }

            int length = stoi(s.substr(i, j-i));
            i = j+1;
            j = i + length;
            ans.push_back(s.substr(i, length));

            i = j;
        }

        return ans;
    }
};

Fix this !
