How to add an Item to a Set in Ruby ?

In Ruby, you can use the Set class to represent a Set. To add an item to a Set, you can use the add method provided by the Set class.

In this example,

We create a Set named numbers containing some integer elements.
We use the add method of numbers to add a new integer element, such as 6, to the set.
Now, numbers contains the added element 6.

require 'set'

numbers = Set.new([1, 2, 3, 4, 5])
numbers.add(6)
puts "Numbers: { " + numbers.to_a.join(' ') + " }"

Numbers: { 1 2 3 4 5 6 }

In this example,

We create a Set named fruits containing some string elements.
We use the add method of fruits to add a new string element, such as 'Orange', to the set.
Now, fruits contains the added element 'Orange'.

require 'set'

fruits = Set.new(['Apple', 'Banana', 'Cherry'])
fruits.add('Orange')
puts "Fruits: { " + fruits.to_a.join(' ') + " }"

Fruits: { Apple Banana Cherry Orange }
