Given two fractions, your task is to check if the values of the two fractions are equivalent or not.
Two integers A and B are represent for the first fraction.
Two integers C and D are represent for the second fraction.
For example,
Even if the first fraction is 5/10 and the second fraction is 1/2, so the result is "the same".
Even if the first fraction is 15/-20 and the second fraction is -18/24, so the result is "the same".
Even if the first fraction is 7/9 and the second fraction is 5/1, so the result is "difference".
Input
Users are required to enter a 4 integers A, B, C, D (-1000 ≤ A, B, C, D ≤ 1000) using the keyboard (STDIN).
Output
Please print out the checking result.
