How to Sort a String Array in Dictionary Order in Ruby - Step by Step Examples
How to Sort a String Array in Dictionary Order in Ruby ?
Answer
To sort a string array in Ruby in dictionary order, you can use the `sort` method. To sort in descending order, you can use the `sort` method with a custom comparator or reverse the array after sorting.
✐ Examples
1 Sort String Array Ascending
In this example,
- We create an array `words` with unsorted elements.
- We use the `sort` method with the array for ascending order.
- We print the sorted array.
Ruby Program
words = ["banana", "apple", "orange", "grape"]
words.sort!
puts "Sorted Array Ascending:\n"
words.each { |word| puts word }
Output
Sorted Array Ascending: apple banana grape orange
2 Sort String Array Descending
In this example,
- We create an array `words` with unsorted elements.
- We use the `sort` method with a custom comparator or reverse the array after sorting for descending order.
- We print the sorted array.
Ruby Program
words = ["banana", "apple", "orange", "grape"]
words.sort! { |a, b| b <=> a }
puts "Sorted Array Descending:\n"
words.each { |word| puts word }
Output
Sorted Array Descending: orange grape banana apple
