407046: GYM102697 017 Chem Lab: Cross the Charges

While preparing for Chemistry Lab in Science Olympiad, you are taught to "cross your charges" when calculating the molecular coefficients given the charges: using the charges of two bonded ions, you swap the two values to obtain the molecular coefficients. For example, a molecule made of two ions with charges of 4 and 3 would have coefficients of 3 and 4, respectively.

The only line of input contains two space-separated integers a and b representing the charges of a and b, respectively.

Output two space-separated integers c and d: the coefficients of each ion given their charges. These can be calculated by swapping a and b (crossing the charges).
