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,
- We have an array named
int_array
containing integers. - We use the
shuffle
method to shuffleint_array
. - 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,
- We have an array named
str_array
containing strings. - We use the
shuffle
method to shufflestr_array
. - 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
