The frequency of a sound doubles for every increase of $1$ octave in pitch. If the pitch of a sound with frequency $X$ hertz is raised by $Y$ octaves, what will its frequency be in hertz? ## Constraints * $1 \leq X \leq 444$ * $1 \leq Y \leq 3$ * All input values are integers. ## Input The input is given from Standard Input in the following format: $X$ $Y$ [samples]

Samples

Input #1

110 2

Output #1

440

For a sound $2$ octaves above a sound with frequency $110$ hertz, its frequency is $110 \times 2 \times 2 = 440$ hertz.

Input #2

233 3

Output #2

1864

For a sound $3$ octaves above a sound with frequency $233$ hertz, its frequency is $233 \times 2 \times 2 \times 2 = 1864$ hertz.

Input #3

432 1

Output #3

864

For a sound $1$ octave above a sound with frequency $432$ hertz, its frequency is $432 \times 2 = 864$ hertz.
