B. Weird Subtraction Processtime limit per test1 secondmemory limit per test256 megabytesinputstandard inputoutputstandard outputYou have two variables a and b. Consider the following sequence of actions performed with these variables: If a = 0 or b = 0, end the process. Otherwise, go to step 2; If a ≥ 2·b, then set the value of a to a - 2·b, and repeat step 1. Otherwise, go to step 3; If b ≥ 2·a, then set the value of b to b - 2·a, and repeat step 1. Otherwise, end the process.Initially the values of a and b are positive integers, and so the process will be finite.You have to determine the values of a and b after the process ends.InputThe only line of the input contains two integers n and m (1 ≤ n, m ≤ 1018). n is the initial value of variable a, and m is the initial value of variable b.OutputPrint two integers — the values of a and b after the end of the process.ExamplesInput12 5Output0 1Input31 12Output7 12NoteExplanations to the samples: a = 12, b = 5  a = 2, b = 5  a = 2, b = 1  a = 0, b = 1; a = 31, b = 12  a = 7, b = 12.
