Determine if a Number is a Power of Three

Determine if a Number is a Power of Three

You are given an integer n. Your task is to determine whether n is a power of three.

An integer n is said to be a power of three if there exists an integer k such that \(n = 3^k\), where \(k \geq 0\). For example, 1 (\(3^0\)), 3 (\(3^1\)), 9 (\(3^2\)), 27 (\(3^3\)) are all powers of three, whereas 0, 2, 45, etc. are not.

You need to read the input from stdin and output your answer to stdout. Print True if the given number is a power of three, and False otherwise.

inputFormat

The input consists of a single integer n provided via stdin.

outputFormat

Output a single line containing either True or False depending on whether n is a power of three.
