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]
