Ruby Array – Initialization Solution

In this post, we will solve Ruby Array – Initialization HackerRank Solution. This problem (Ruby Array – Initialization) is a part of HackerRank Ruby series.

Task

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 = []

• nitialize 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]

Solution – 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)
