Problem Statement

Read two integers $A$ and $B$. Each input representation may start with a + or - sign. Print the normalized integer values, separated by one space.

Input

One line with the integer representations $A$ and $B$, separated by whitespace.

Output

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

Subtasks

• Subtask 1 — 100 points: $-10^9\le A,B\le10^9$. Each value contains digits and may have one leading + or - sign.

Examples

Input

+5 -3

Output

5 -3

Explanation

The line contains two tokens, +5 and -3. Splitting produces those strings. int("+5") is $5$ and int("-3") is $-3$. Printing the integers gives 5 -3, without the optional plus sign.
