### Problem Statement

The magnitude of an earthquake is a logarithmic scale of the energy released by the earthquake. It is known that each time the magnitude increases by $1$, the amount of energy gets multiplied by approximately $32$.
Here, we assume that the amount of energy gets multiplied by exactly $32$ each time the magnitude increases by $1$. In this case, how many times is the amount of energy of a magnitude $A$ earthquake as much as that of a magnitude $B$ earthquake?

### Constraints

• $3\leq B\leq A\leq 9$
• $A$ and $B$ are integers.

### Input

Input is given from Standard Input in the following format:

$A$ $B$


### Output

Print the answer as an integer.

### Sample Input 1

6 4


### Sample Output 1

1024


$6$ is $2$ greater than $4$, so a magnitude $6$ earthquake has $32\times 32=1024$ times as much energy as a magnitude $4$ earthquake has.

### Sample Input 2

5 5


### Sample Output 2

1


Earthquakes with the same magnitude have the same amount of energy.
