What is the error in this code...not giving right output

@garganshul151
I have fixed the mistake, but still it will give TLE, because your approach is incorrect.

what should be the approach to avoid TLE?

also why you did a=no++ in the corrected code ??


I did a = no++, because to check a new number each time.

i have done a++ at last will it not able to check new number every time?

but you are also modifying the value of a in the loop.
