[Hackerrank] Intro to Conditional Statements

Objective

 

In the challenge, we learn about conditional statements. Check out the Turorial tab for learning materials and an instructional video.

 

Task

 

Given an integer, n, perform the following confitional 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.

 

Sample Input 0

3

 

Sample Output 0

Weird

 

Sample Input 1

24

 

Sample Output 1

Not Weird

 

Explanation

 

Sample Case 0: n = 3

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

 

Sample Case 1:n = 24

n > 20 and n is even, so it is not weird. Thus, we print Not Weird
