Problem type

Bob is practicing square root decomposition!

The problem Bob is doing involves breaking a number N into B groups. It is said to be optimal if B is closest to \sqrt{N}.

He currently has 2 candidates for B: integers i and j. If i and j are squared, which one is closer to N?

The data guarantee that one candidate will be closer than the other.

Constraints

1 \le N, i, j \le 10^4

i \ne j

Input Specification

The first line will contain N.

The second line will contain i.

The third and final line will contain j.

Output Specification

On one line, output 1 if i^2 is closer to N or 2 if j^2 is.

    Possible spoiler, but I had tried to square the distances between N and i/j squared to find the positive distance, but that caused a WA .Since the distances are being compared and their actual value doesn't matter, why wouldn't this work?
