The – is an inbuilt method in Ruby that returns a new set built by duplicating the set, removing every element that appears in the given enumerable object.

Syntax: s1.name – s2.name

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 program to illustrate the - method 
  
#requires the set 
require "set"
  
    s1 
    = Set[1, 2, 4] s2 = Set[1, 2, 3] 
  
#+ method used 
    s3 
    = s1 - s2 
  
#Prints the s3 
               puts s3 

Output:

Set: {4}

Example 2:

#Ruby program to illustrate the - method 
  
#requires the set 
require "set"
  
    s1 
    = Set[1, 2, 4] s2 = Set[6, 5, 3] 
  
#& method used 
    s3 
    = s1 - s2 
  
#Prints the s3 
               puts s3 

Output:

Set: {1, 2, 4}
