This problem is worth 5 points.

For an engineering challenge, you have to make a project which has a certain height $$$n$$$, with a tolerance of $$$k$$$. This means that any height between $$$n$$$ - $$$k$$$ and $$$n$$$ + $$$k$$$ will be acceptable. For example, if $$$n$$$ was equal to 5, and $$$k$$$ was equal to 2, any height between 3 and 7, inclusive, would be acceptable.

Given these values $$$n$$$ and $$$k$$$, figure out the lower and upper height limit for the engineering project.

Input

The input consists of two lines: positive integers $$$n$$$ and $$$k$$$, each on separate lines.

Output

Output two lines. On the first line, output the lower height limit, as described above. On the second line, output the upper height limit, as described above.
