A strange grid has been recovered from an old book. It has $5$ columns and infinite number of rows. The bottom row is considered as the first row. First few rows of the grid are like this:

    ..............

    ..............

    20 22 24 26 28

    11 13 15 17 19

    10 12 14 16 18

     1  3  5  7  9

     0  2  4  6  8

The grid grows upwards forever!

Your task is to find the integer in $c$<sup>th</sup> column in $r$<sup>th</sup> row of the grid.

Input Format

There will be two integers r and c separated by a single space.  

**Constraints**  


* $ 1 \le r  \le 2 * 10^9$

* $1 \le c \le 5$

Rows are indexed from bottom to top and columns are indexed from left to right.

Output Format

Output the answer in a single line.
