Starters 86 rating dropped from 1523 to 1248 due to plagiarism

Describe your bug

My rating goes down from 1523 to 1248 due to some plagiarism but I want to know with whom my code matches or any explanation. Kindly give me an explanation and other details so I can know what happened properly. If you can, then please do check again for plagiarism. I opened my account after a long time and saw first this and it’s very demotivating for me.


Additional info

The question was also the 3rd question which was easy.
