[HackerRank] Day 3: Intro to Conditional Statements

Objective

In this challenge, we're getting started with conditional statements. Check out the Tutorial tab for learning materials and an instructional video!

Task

Given an integer, n, perform the following conditional actions:

If is odd, print Weird

If is even and in the inclusive range of 2 to 5, print Not Weird

If is even and in the inclusive range of 6 to 20, print Weird

If is even and greater than 20, print Not Weird

Complete the stub code provided in your editor to print whether or not n is weird.

 

Input Format

A single line containing a positive integer, n.

 

Constraints

1 <= n <= 100

 

Output Format

Print Weird if the number is weird; otherwise, print Not Weird.

 

Sample Input 0

3 

 

Sample Output 0

Weird 

 

Sample Input 1

24 

 

Sample Output 1

Not Weird 

 

Explanation

Sample Case 0:

is odd and odd numbers are weird, so we print Weird.

Sample Case 1:

and is even, so it isn't weird. Thus, we print Not Weird.

public class Solution {

	public static void main(String[] args) {
		Scanner scan = new Scanner(System.in);
		int n = scan.nextInt();
		scan.close();
		String ans = "";

		// if 'n' is NOT evenly divisible by 2 (i.e.: n is odd)
		if (n % 2 == 1)
			ans = "Weird";
		// Complete the code
		else if (n >= 2 && n <= 5)
			ans = "Not Weird";
		else if (n >= 6 && n <= 20)
			ans = "Weird";
		else if (n > 20)
			ans = "Not Weird";
		System.out.println(ans);
	}
}
