Can you please explain the reason.

There may be whitespace at the end of the last line. Usually there is at least a newline character at the end of every line, including the last one.

Precompute whether each possible input is prime or not.

sorry I don't understand what should I do
I mean that the code is doing it right >> i think

Before you read any input compute whether each possible N is prime.
