HackerRank Ruby Array Initialization Solution

Hello coders, In this post, you will learn how to solve HackerRank Ruby Array Initialization Solution. This problem is a part of the Ruby Tutorial series. One more thing to add, don’t straight away look for the solutions, first try to solve the problems by yourself. If you find any difficulty after trying several times, then look for the solutions.

HackerRank Ruby Array Initialization Solution

Let’s get started with Ruby Array Initialization Solution

Problem Statement

One of the most commonly used data structures in Ruby is a Ruby Array, and below we see various methods of initializing a ruby array.

Your task is to initialize three different variables as explained below.

• Initialize an empty array with the variable name array

Hint

array = Array.new

or

array = []

• Initialize an array with exactly one nil element in it with the variable name array_1

Hint

array_1 = Array.new(1)

or

array_1 = [nil]

• Initialize an array with exactly two elements with value 10 in it using the variable name array_2.

Hint

array_2 = Array.new(2, 10)

or

array_2 = [10, 10]

HackerRank Ruby Array Initialization Solution

# Initialize 3 variables here as explained in the problem statement
array = Array.new(0)
array_1 = Array.new(1)
array_2 = Array.new(2,10)
