Ruby program to check a set is a superset of another set

Last Updated : December 15, 2025

Problem Solution

In this program, we will create two objects of the Set class and add items into created sets. Then we will check a set is a superset of another set using the ">=" operator.

Program/Source Code

The source code to check a set is a superset of another set is given below. The given program is compiled and executed successfully.

# Ruby program to check a set is a 
# superset of another set

require 'set';

setObj1 = Set.new();
setObj2 = Set.new();

setObj1.add(101);
setObj1.add(102);
setObj1.add(103);
setObj1.add(104);
setObj1.add(105);

setObj2.add(103);
setObj2.add(104);
setObj2.add(105);

if setObj1 >= setObj2
    puts "setObj1 is the superset of setObj2";
else
    puts "setObj1 is not the superset of setObj2";
end

Output

setObj1 is the superset of setObj2

Explanation

In the above program, we imported the "set" package using the "require" statement. Then we created two objects setObj1, setObj2 of the Set class using the new() method and added items into created set using add() method of the Set class. After that, we checked set setObj1 is the superset of setObj2 using the ">=" operator and printed the appropriate message.
