How to Reverse an Array in Ruby - Step by Step Examples

How to Reverse an Array in Ruby ?

Answer

To reverse an array in Ruby, you can use the reverse method.


✐ Examples

1 Reverse Array of Integers

In this example,

  1. We have an array named int_array containing integers.
  2. We use the reverse method on int_array to reverse the elements.
  3. We print the reversed array to demonstrate the reversal.

Ruby Program

int_array = [1, 2, 3, 4, 5]
reversed_array = int_array.reverse
puts "Reversed Array: #{reversed_array}"

Output

Reversed Array: [5, 4, 3, 2, 1]

2 Reverse Array of Strings

In this example,

  1. We have an array named str_array containing strings.
  2. We use the reverse method on str_array to reverse the elements.
  3. We print the reversed array to demonstrate the reversal.

Ruby Program

str_array = ["apple", "banana", "cherry"]
reversed_array = str_array.reverse
puts "Reversed Array: #{reversed_array}"

Output

Reversed Array: ["cherry", "banana", "apple"]

Summary

In this tutorial, we learned How to Reverse an Array in Ruby language with well detailed examples.
