The above code is running perfectly in codeblocks but is showing a error while submitting

hello @mahi.1305
check output format of this problem.
and then print only those things that are mentioned there.

also no need of such conditions. given input will always be valid

#3

Sir,
i added these conditions for the negative number.
because during submission of the code an error message is being displayed asking to apply a code for negative numbers too.

as per constraints n will be always positive so no need to handle negative case.

ignore this message.

remember one thing , whatever is mentioned in constraint section of any will always be followed on given input, so there is no need to add additional code for handling constraint voilation
