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: $A$ $B$ [samples]

Samples

Input #1

6 4

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.

Input #2

5 5

Output #2

1

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