Problem

You should know the very tiny game sometimes called "Number guess". The computer thinks about a number between a agreed area, in this case from 1 to 1000. Then you guess the number and the computer answers if it's to low '<' or to high '>'. The objective of the game is to guess the number in as few as possible tries.

In this Problem it is a littlebit different. The program gets a number and tries to solve it with few as possible tries. So for example, if my number is 768, it first tries 500 and returns not only the number, but also the '<'-sign, because this number is to low. Then it adds 250, which is fortunately 500/2, because it was to low. So now the guess is 750, and again '<'. But now it adds the half again, which is 125. Then the number gets to high, because it is now 875, so it adds '>'. Next time it subtracts the half, which is now 62.5. Next number would be 812.5, but it's rounded to 813, again to high. After a while 768 is tried. And as it is the right one, a equal-sign is added.

Importance is really the right rounding. I'm feeling sorry that the original game isn't working in golf, but I hope you will understand it. By the way: It should also work with more numbers, so just add a blank line between them in Output.
