@nigamshubham1998,
Your code will give a wrong answer for the following input:

Input:
92
Correct output:
92
Your output:
02

It is also mentioned in the question The decimal representation of the final number shouldn’t start with a zero.

#3

@nigamshubham1998,
Similarly if for the input:

Input:
999
Correct output:
900
Your output:
000
