firstly, the topic says not able to submit
Is it literally that or do you mean you got WA?

Secondly, format your code using three backticks (```) like this

T = int(input())
blah blah
    indent (makes code easier to read)

Thirdly, you do NOT need to check for constraints in your code, so your if conditions might be the mistake
