Difficulty—

You are given an integer $N$. Compute and output the value of $2^N-2N$. ## Constraints * $N$ is an integer between $1$ and $11$, inclusive. ## Input The input is given from Standard Input in the following format: $N$ [samples]

Samples

Input #1

Output #1

0

The value of $N$ given in this input is $1$, so output the value of $2^1 - 2 \times 1$, which is $0$.

Input #2

Output #2

0

The value of $N$ given in this input is $2$, so output the value of $2^2 - 2 \times 2$, which is $0$.

Input #3

Output #3

2026

The value of $N$ given in this input is $11$, so output the value of $2^{11} - 2 \times 11$, which is $2026$.
