Description
Shou Tucker is an outstanding biologist, trying to prove his ability through his new experiment.
However, his cute daughter, Nina, accidentally delete his research data about the number of each animal in the lab.
Fortunately, there is some remaining information:
(1) There are two kinds of animals in the lab.
(2) The number of legs for the two animals is A and B (A>=B), respectively.
(3) The total number of legs is C.
(4) The total number of animals is D.
As his assistant, your job is to help him recover the data (E and F, which represent the number of each animal).
Hope Nina will be a good girl next time ;)
Input
Four integers, A, B, C, and D , separated by a blank.
Note that (2 <= A, B <= 20)
Output
E and F (1 <= E, F <= 1000) separated by a blank, representing the number of each animal.
Note that you do not need to print '\n' at the end of the output.
