Day 3: Into to Conditional Statements | 30 Days Of Code | HackerRank Solution

Hello coders, today we are going to solve Day 3: Into to Conditional Statements HackerRank Solution in C++, Java and Python.

Objective

In this challenge, we learn about conditional statements.

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.

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.
