Source: Wikipedia

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

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.

Example 0 :-

Sample Input 0

3

Sample Output 0

Weird

Example 1 :-

Sample Input 1

24

Sample Output1

Not Weird

Explanation

Sample Case 0: n=3n is odd and odd numbers are weird, so we print Weird.Sample Case 1:n=24 n>24 and n is even, so it isn’t weird. Thus, we print Not Weird.
