# Exponentiation

## Statement

Given a positive real number $$a$$ and a non-negative integer $$n$$. Calculate $$a^{n}$$ without using loops, ** operator or the built in function math.pow(). Instead, use recursion and the relation $$a^{n} = a \cdot a^{n-1}$$. Print the result.

Form the function power(a, n).

In all the problems input the data using input() and print the result using print().
