With all due respect, if you don't have a question regarding your code, then this is not the place to post it.

Please reserve this thread for code related Q&A only.

PS: I haven't tested your code, but it looks clever. Well done!

Answer 2

Md Shakil
Your code logic is good, (better than mine) but your output does not meet the challenge requirements.

Your outputs -> valid, invalid.
Expected outputs -> Valid, Invalid.

Good luck
