You are given integers $ A $ and $ C $ , and non-negative integers $ B $ and $ D $ . If $ \frac{A}{B}`; if $ \frac{A}{B}=\frac{C}{D} $ , print `=`.

The input is given from Standard Input in the following format: > $ A $ $ B $ $ C $ $ D $

Print one of ``, and `=` according to the Problem Statement.

### Sample Explanation 1 We have $ \frac{1}{2}>\frac{1}{3} $ , so you should print `>`. ### Sample Explanation 2 We have $ \frac{-3}{-6}=\frac{1}{2} $ , so you should print `=`. Note that the given fractions may be reducible, and the given integers may be negative. ### Sample Explanation 3 We have $ \frac{-1}{3}
