c++ question on 'It's a sign' challenge

Hey there. I came up with a rather complicated solution (well, not really) to the "it's a sign" challenge. In two cases, the code does not quite work and I cannot think of why that is the case. Any help or hints would be happily appreciated. #include <iostream> #include <sstream> #include <string> #include <vector> #include <algorithm> int main() { std::string str = "CATS MONDYAS RACeCAR TACOS"; std::string str2(str.rbegin(), str.rend()); //reverse string items int count = 0; std::vector<std::string> vecStr; std::vector<std::string> vecStr2; std::stringstream ss(str); //convert str into stringstream std::stringstream ss2(str2); //convert str into stringstream std::string strTemp, strTemp2; while (ss >> strTemp) //optional with delimiter -> getline(ss, strTemp, ',') { vecStr.push_back(strTemp); } while (ss2 >> strTemp2) //optional with delimiter -> getline(ss, strTemp, ',') { vecStr2.push_back(strTemp2); } std::reverse(vecStr2.begin(), vecStr2.end()); //reset order of elements to original //comparing elements in two vectors for (std::size_t i = 0; i != vecStr.size(); i++) { if (vecStr[i] == vecStr2[i]) count++; } if (count != 0) std::cout << "OPEN"; else std::cout << "TRASH"; }

Just wanna remind you to pay extra attention on the required output formatting. I seen someone failed it for one different letter case, so, careful with the outputs.

Is that the exact code of your solution? If it is, you hard coded the case instead of taking inputs. Btw, please check letter case like Ipang said.

I didn't try the challenge. But this approach which is very different to yours should work with 4 inputs. Just for your reference. https://code.sololearn.com/chis40AWH5Ex/?ref=app

This is not the exact code, of course (no input). Just for demonstration purposes. Thank you both! I will check. By the way, I did use Open and Trash respectively… so there shouldn‘t be an issue with the output…
