How to get Sub Array in Ruby

How to get Sub Array in Ruby ?

Answer

To get a sub-array in Ruby, you can use array slicing.


✐ Examples

1 Sub-array of Integer Array

In this example,

  1. We create an integer array named numbers with some values.
  2. We then use array slicing to get a sub-array from index 2 to index 4 (inclusive).
  3. Finally, we print the sub-array.

Ruby Program

numbers = [1, 2, 3, 4, 5]
sub_array = numbers[2..4]
puts "Sub-array: #{sub_array}"

Output

Sub-array: [3, 4, 5]

2 Sub-array of Character Array

In this example,

  1. We create a character array named characters with some values.
  2. We then use array slicing to get a sub-array from index 1 to index 3 (inclusive).
  3. Finally, we print the sub-array.

Ruby Program

characters = ['a', 'b', 'c', 'd', 'e']
sub_array = characters[1..3]
puts "Sub-array: #{sub_array}"

Output

Sub-array: ["b", "c", "d"]
