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

How to Shuffle an Array in Ruby ?

Answer

In Ruby, you can shuffle an array using the built-in shuffle method, which implements the Fisher-Yates shuffle algorithm.


✐ Examples

1 Shuffle Array of Integers

In this example,

  1. We have an array named int_array containing integers.
  2. We use the shuffle method to shuffle int_array.
  3. We print the shuffled array to demonstrate the shuffling.

Ruby Program

int_array = [1, 2, 3, 4, 5]
shuffled_array = int_array.shuffle
puts 'Shuffled Array:', shuffled_array.join(' ')

Output

Shuffled Array: 4 1 2 5 3

2 Shuffle Array of Strings

In this example,

  1. We have an array named str_array containing strings.
  2. We use the shuffle method to shuffle str_array.
  3. We print the shuffled array to demonstrate the shuffling.

Ruby Program

str_array = ['apple', 'banana', 'cherry']
shuffled_array = str_array.shuffle
puts 'Shuffled Array:', shuffled_array.join(' ')

Output

Shuffled Array: banana apple cherry
