Power of Three - The Coding Shala

Home >> Programming >> Power of Three

 In this post, we will learn how to find if the Given number is Power of Three or not, and will implement its solution in Java.

Power of Three Problem

Given an integer n, return true if it is a power of three. Otherwise, return false. An integer n is a power of three if there exists an integer x such that n == 3^x.

Example 1:
Input: n = 27
Output: true

Example 2:
Input: n = 0
Output: false

Example 3:
Input: n = 9
Output: true

Power of Three Java Solution

Approach 1

Using loop.

Java Program: 

class Solution {
    public boolean isPowerOfThree(int n) {
        if(n <= 0) return false;
        while(n%3 == 0) {
            n = n/3;
        }
        return n == 1;
    }
}
