To remove Plagiarism🟥🟨🟧🟩🟦🟪
1) Use your Own template✅
2) Change Variables ✅
3) Try to read input in unique style✅
4) Understand the code and write in your style ✅
5) Write whole code in main function / write in diffrent function✅
6) Change Function name solve()=> unique✅
7) If possible change flow of the problem (if it doesn't impact the logic of code)✅
there are so many other things to avoid Plagiarism🔥🔲
