How to Rotate Elements in an Array in Ruby

How to Rotate Elements in an Array in Ruby ?

Answer

To rotate elements in an array using Ruby, you can use the built-in methods like `rotate` or implement a custom rotation function.


✐ Examples

1 Rotate Array of Integers

In this example,

  1. We have an array named int_array containing integers.
  2. We use the built-in rotate method to rotate the array by a specified number of positions.
  3. We print the rotated array to demonstrate the rotation.

Ruby Program

int_array = [1, 2, 3, 4, 5]
positions = 2
rotated_array = int_array.rotate(positions)
puts "Rotated Array: #{rotated_array}"

Output

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

2 Rotate Array of Strings

In this example,

  1. We have an array named str_array containing strings.
  2. We use the built-in rotate method to rotate the array by a specified number of positions.
  3. We print the rotated array to demonstrate the rotation.

Ruby Program

str_array = ["apple", "banana", "cherry", "date", "fig"]
positions = 3
rotated_array = str_array.rotate(positions)
puts "Rotated Array: #{rotated_array}"

Output

Rotated Array: ["date", "fig", "apple", "banana", "cherry"]
