ProgramGuruTo get the size of a set in Ruby, you can use the size method on the set.
In this example,
set1 using the Set class with some elements.size method on the set object set1 to get the number of elements in the set.size method returns the size of the set.require 'set'
set1 = Set.new(['apple', 'banana', 'cherry'])
# Get the size of the set
size = set1.size
# Print the size
puts "Size of set1: #{size}"Size of set1: 3
In this example,
empty_set using the Set class.size method on the set object empty_set to get the number of elements in the set.size method returns 0.require 'set'
empty_set = Set.new
# Get the size of the empty set
size = empty_set.size
# Print the size
puts "Size of empty_set: #{size}"Size of empty_set: 0
