HackerRank – 30 Days of Code – Day 3: Intro to Conditional Statements – Ruby Program

Objective

In this challenge, we’re getting started with conditional statements. Check out the Tutorial tab for learning materials and an instructional video!

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 isn’t weird. Thus, we print Not Weird.

Ruby Program

#!/bin/ruby

N = gets.strip.to_i

if (N%2 == 1)
    puts "Weird"
    
elsif (N%2 ==0 && N>1 && N<6)
    puts "Not Weird"
    
elsif (N%2 == 0 && N>=6 && N<=20)
    puts "Weird"

    
elsif (N%2 == 0 && N>20 && N<101)
    puts "Not Weird"
end
