Problem statment:
https://www.hackerrank.com/challenges/java-if-else/problem

In this challenge, we test your knowledge of using if-else conditional statements to automate decision-making processes.
An if-else statement has the following logical flow:

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

If n is odd, print Weird
If n is even and in the inclusive range of 2 to 5, print Not Weird
If n is even and in the inclusive range of 6 to 20, print Weird
If n is even and greater than 20, print Not 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: n=3, where n is odd and odd numbers are weird, so we print Weird.
Sample Case 1: n=24, where n>20 and n is even, so it isn’t weird. Thus, we print Not Weird.
