You have used the wrong logic here. You are just sorting the numbers in decreasing order and then concatenating them to form the answer. This doesn’t always work. If two numbers are 10, 1 then, your answer will be 101 but the correct answer is 110

I hope I’ve cleared your doubt. I ask you to please rate your experience here
