Sohag loves maths so his brother Sohag2 gave him a math problem to solve.
He gave Sohag an integer \(X\) and told him to do the following operation \( 10^{100^{100}} \) times:

Multiply the current number by \(3\).
Add \(3\) to the result
Multiply the result by \(2\)
Divide the result by \(6\).
Subtract \(1\) from the answer.
Sohag will be calculating this until the heat death of the universe. But can you write a code to get the answer faster?

The first line contains an integer \(X\).

 It is given that  \(-3 \times 10^6 \leq X \leq 3 \times 10^6 \)

Print the output after all the operations
