Power of Three
As a Systems Engineer at Tata Consultancy Services, I deliver exceptional software products for mobile and web platforms, using agile methodologies and robust quality maintenance. I am experienced in performance testing, automation testing, API testing, and manual testing, with various tools and technologies such as Jmeter, Azure LoadTest, Selenium, Java, OOPS, Maven, TestNG, and Postman.
I have successfully developed and executed detailed test plans, test cases, and scripts for Android and web applications, ensuring high-quality standards and user satisfaction. I have also demonstrated my proficiency in manual REST API testing with Postman, as well as in end-to-end performance and automation testing using Jmeter and selenium with Java, TestNG and Maven. Additionally, I have utilized Azure DevOps for bug tracking and issue management.
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<sup>x</sup>.
LeetCode Problem - 326
class Solution {
// This method checks if a given integer 'n' is a power of three.
public boolean isPowerOfThree(int n) {
// Iterate through a loop while 'n' is greater than 0.
while(n > 0){
// If 'n' is equal to 1, it means 'n' is a power of three, so return true.
if(n == 1)
return true;
// If 'n' is not divisible by 3 (i.e., 'n' is not a multiple of 3), break the loop.
if(n % 3 != 0)
break;
// Divide 'n' by 3 to check the next power of three.
n /= 3;
}
// If the loop finishes and 'n' is not equal to 1, it means 'n' is not a power of three, so return false.
return false;
}
}
