How to Sort Characters in String in Ruby - Step by Step Examples

How to Sort Characters in String in Ruby ?

Answer

In Ruby, you can sort characters in a string using the chars method to convert the string into an array of characters, then sorting the array, and joining it back into a string.


✐ Examples

1 Sort Characters in Ascending Order

In this example,

  1. We create a string named str.
  2. We convert the string into an array of characters using the chars method.
  3. We sort the array of characters in ascending order.
  4. We join the sorted array of characters back into a string.
  5. Finally, we print the sorted string in ascending order.

Ruby Program

str = 'hello world'
sorted_str = str.chars.sort.join
puts 'Sorted string in ascending order: ' + sorted_str

Output

Sorted string in ascending order:  dehllloorw

2 Sort Characters in Descending Order

In this example,

  1. We create a string named str.
  2. We convert the string into an array of characters using the chars method.
  3. We sort the array of characters in descending order.
  4. We join the sorted array of characters back into a string.
  5. Finally, we print the sorted string in descending order.

Ruby Program

str = 'hello world'
sorted_str = str.chars.sort.reverse.join
puts 'Sorted string in descending order: ' + sorted_str

Output

Sorted string in descending order: wroolllhed
