# Hackerrank Java If-Else Solution

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:

Source: Wikipedia

Given an integer, , perform the following conditional actions:

• If  is odd, print Weird
• If  is even and in the inclusive range of  to , print Not Weird
• If  is even and in the inclusive range of  to , print Weird
• If  is even and greater than , print Not Weird

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

Input Format

A single line containing a positive integer, .

Constraints

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.
