P6483 [COCI 2010/2011 #4] PARKET
Description
There is an $n$ by $m$ grid. The cells on the outer border are red, and all other cells are black.
Given the number of red cells $r$ and the number of black cells $b$, find a feasible pair of values $n$ and $m$.
Input Format
The input consists of one line with two integers, representing the number of red cells $r$ and the number of black cells $b$.
Output Format
Output one line with two integers, representing the number of rows $n$ and the number of columns $m$ of the grid. If there are multiple solutions, output the one with the largest $n$.
Explanation/Hint
#### Explanation of Sample 2
The output grid is shown in the figure: light-colored cells represent red, and dark-colored cells represent black.

#### Constraints
For all testdata, it is guaranteed that $8 \leq r \leq 2 \times 10^6$ and $1 \leq b \leq 2 \times 10^{6}$. It is guaranteed that at least one solution exists.
