Ruby | Set disjoint? function

Last Updated : 07 Jan, 2020

The disjoint? is an inbuilt method in Ruby that returns true if the set and the given set have no element in common.

Syntax: s1.disjoint?(s2) Parameters: The function does not takes any parameter. Return Value: It returns a new set built by duplicating the set, removing every element that appears in the given enumerable object.

Example 1:

Ruby

# Ruby program to illustrate the disjoint? method 
 
# requires the set 
require "set"
 
s1 = Set[1, 2, 4]
s2 = Set[1, 2, 3] 
 
# difference method used
s3 = s1.disjoint?(s2)
 
# Prints the s3 
puts s3

Output:

false

Example 2:

Ruby

# Ruby program to illustrate the disjoint? method 
 
# requires the set 
require "set"
 
s1 = Set[8, 5, 4]
s2 = Set[1, 2, 3] 
 
# difference method used
s3 = s1.disjoint?(s2)
 
# Prints the s3 
puts s3

Output:

true
