How to check if Two Sets are Equal in Ruby - Step by Step Examples



How to check if Two Sets are Equal in Ruby ?

Answer

In Ruby, you can check if two sets are equal by comparing them using the '==' operator.



✐ Examples

1 Check Equality of Two Sets

In this example,

  1. We define two sets, set1 and set2, containing elements of the sets.
  2. We use the '==' operator to compare the sets for equality.
  3. If the two sets contain the same elements, the '==' operator returns 'true'; otherwise, it returns 'false'.

Ruby Program

require 'set'

set1 = Set.new([1, 2, 3, 4])
set2 = Set.new([1, 2, 3, 4])

are_equal = set1 == set2

puts are_equal

Output

true

2 Check Equality of Unequal Sets

In this example,

  1. We define two sets, set1 and set2, containing elements of the sets.
  2. We use the '==' operator to compare the sets for equality.
  3. If the two sets contain different elements or have a different number of elements, the '==' operator returns 'false'.

Ruby Program

require 'set'

set1 = Set.new([1, 2, 3, 4])
set2 = Set.new([4, 3, 2, 1])

are_equal = set1 == set2

puts are_equal

Output

true

In this tutorial, we learned How to check if Two Sets are Equal in Ruby language with well detailed examples.
