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

Test cases does not have any string in which '?' is there so when I am only using a delimiter as '?' the solution is getting ACCEPTED

I have pasted my code here which is getting accepted rather it should fail for cases where '?' is present in string.

string encode(vector& strs) {
string s="";
for(string ch : strs){
s+=ch;
s.push_back('?');
}
return s;
}

vector<string> decode(string s) {
    vector<string>v;
    string str="";
    for(char ch : s){
        if(ch=='?'){
            v.push_back(str);
            str="";
            continue;
        }
        str.push_back(ch);
    }
    if(str!="")
        v.push_back(str);
    return v;
