If you are a fan of Harry Potter, you wocould know the world of magic has its own currency system -- As Hagrid explained it to Harry, "Seventeen silver sickles to a galleon and twenty-nine knuts to a sickle, it's easy enough. "Your job is to write a program
Compute a + B where A and B are given in the standard form of "galleon. Sickle. Knut" (Galleon is an integer in [0, 10^{7], sickle is an integer in [0, 17), and Knut is an integer in [0, 29 )).}

Input specification:

Each input file contains one test case which occupies a line with A and B in the standard form, separated by one space.

Output specification:

For each test case you shoshould output the sum of A and B in one line, with the same format as the input.

Sample input:

3.2.1 10.16.27

Sample output:

14.1.28
