How to Sort an Array in Ruby - Step by Step Examples
How to Sort an Array in Ruby ?
Answer
To sort an array in Ruby, you can use the sort method.
✐ Examples
1 Sort Integer Array in Ascending Order
In this example,
- We create an integer array named
numbers
with values 5, 2, 8, 1, 6. - We use the
sort
method to sort the array in ascending order. - Finally, we print the sorted array
numbers
to the console.
Ruby Program
numbers = [5, 2, 8, 1, 6]
numbers.sort!
puts "Sorted array in ascending order: #{numbers}"
Output
Sorted array in ascending order: [1, 2, 5, 6, 8]
2 Sort Integer Array in Descending Order
In this example,
- We create an integer array named
numbers
with values 5, 2, 8, 1, 6. - We use the
sort
method with a block that sorts in descending order. - Finally, we print the sorted array
numbers
to the console.
Ruby Program
numbers = [5, 2, 8, 1, 6]
numbers.sort! { |a, b| b <=> a }
puts "Sorted array in descending order: #{numbers}"
Output
Sorted array in descending order: [8, 6, 5, 2, 1]
