HackerRank Day 3: Intro To Conditional Statements – 30 Days of Code Solution

In this article, we will be solving HackerRank Day 3: Intro To Conditional Statements problem, part of 30 Days of Code. Majorly, we will use Python3 and Java15 to solve the problem.


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


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.


  • 1 <= n <= 100

Output Format

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

Sample Input 0


Sample Output 0


Sample Input 1


Sample Output 1

Not Weird


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. This, we print Not Weird.

if __name__ == '__main__':
    N = int(input().strip())
    if(N%2 == 1):
    elif(N%2==0) and (N in range(2,7)):
        print("Not Weird")
    elif(N%2==0) and (N in range(6,21)):
    elif(N%2==0) and (N>20):
        print("Not Weird")
