How to find Intersection of Two Sets in Ruby - Step by Step Examples

How to find Intersection of Two Sets in Ruby ?

Answer

In Ruby, you can find the intersection of two sets using the `&` operator or the `intersection` method.


✐ Examples

1 Find Intersection of Two Sets using & Operator

In this example,

  1. We define two arrays representing sets named set1 and set2.
  2. We use the & operator between set1 and set2 to find their intersection.
  3. The resulting array contains elements common to both sets.

Ruby Program

require 'set'

set1 = [1, 2, 3, 4, 5]
set2 = [4, 5, 6, 7, 8]
intersection = set1 & set2
puts intersection

Output

4
5

2 Find Intersection of Two Sets using intersection Method

In this example,

  1. We define two arrays representing sets named set1 and set2.
  2. We call the intersection method on set1 and pass set2 as an argument.
  3. The resulting array contains elements common to both sets.

Ruby Program

require 'set'

set1 = [1, 2, 3, 4, 5]
set2 = [4, 5, 6, 7, 8]
intersection = set1.intersection(set2)
puts intersection

Output

4
5
