410225: GYM103987 A Calculus

Chipmunk is a math genius, and he is extraordinarily good at calculus.

Now Chipmunk gives you a formula and asks you to calculate it in one minute, or you should treat him to dinner. The formula looks like this: $$$$$$ \int_0^{2\pi}\frac{\text{d}x}{(1+\sin^2x)\sqrt{2-\sin^2x}} $$$$$$

Obviously it is impossible to get the accurate answer, so Chipmunk only requires you to tell him the integer part of it.

It can be anything, and has nothing to do with the answer.

Print an integer $$$n\ (1\le n\le 5)$$$, representing the answer to the problem above.

Of course Chipmunk will not tell you the correct answer in the example above!
