You may try the problem here.It already has the function to take care of input/output.

when i compile the code, it shows these errors:

runguard: warning: timelimit exceeded (wall time): aborting command runguard: warning: command terminated with signal 15

can you please check what is wrong with my code ( problem. https://ide.codingblocks.com/s/262051 )

Your code seems fine to me ,I think there is some backend issue (as I tried returning NULL and it still gave TLE!)


this is best site to do this at.

i ran the code in my ide and it was working fine. so i submitted it and it got accepted. thanks for the help

but can you tell me what this error actually means?

Well its no error, instead its just a warning, also it occurs due to compile time out and is generally related to issue with compiler
