Just to clarify my comment, you didn't specify any errors in your code, so we don't have what to answer you. If your code is working without any errors and you want to ask how to make it more clear/optimizable/etc. it's better to ask on codereview if you want to ask for writing program by some algorithm/pseudocode/idea it's better to do on some freelancing platforms. — Alex Golubenko 36 secs ago
