The code works good. current_no=4 and next_no=5, which will break the loop after setting flag = False. Link for my code again for visibility here

On my machine, your solution outputs

yes

My code: Rainbowa

I’m not able to find the test case that is getting failed. Someone please help me with this code.

Will the list contain elements valued only upto 7 or can it take up values like 8 9 also? Like is
1 2 3 4 4 5 6 7 7 8 7 7 6 5 4 4 3 2 1 valid??

1 2 3 4 4 5 6 7 7 8 7 7 6 5 4 4 3 2 1 is not valid. The array can contain elements only upto 7
