Problem Statement

Two integers $A$ and $B$ are provided on one line, separated by a comma. There may be multiple spaces after the comma. Convert both fields to integers, then print them on one line separated by a single space.

Input

One line contains $A$, a comma, and $B$; whitespace may surround the two integers.

Output

Print the two integer values $A$ and $B$, separated by exactly one space.

Subtasks

• Subtask 1 — 100 points: $-10^9\le A,B\le10^9$.

Examples

Input

-7,   +0

Output

-7 0

Explanation

Calling split(",") produces two strings, "-7" and " +0". The int() conversion produces $-7$ and accepts both the leading spaces and the plus sign in the second token, producing integer $0$. The output is -7 0, without a comma.
