Furik loves math lessons very much, so he doesn't attend them, unlike Rubik. But now Furik wants to get a good mark for math. For that Ms. Ivanova, his math teacher, gave him a new task. Furik solved the task immediately. Can you?
You are given a system of equations:
(a, b) (0 ≤ a, b)
Input
n, m (1 ≤ n, m ≤ 1000)
Output
On a single line print the answer to the problem.
