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

Ruby Example: Write a program to check a set is a subset of another set.
Submitted by Nidhi, on February 07, 2022

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 subset of another set using the "<=" operator.

Program/Source Code:

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

# Ruby program to check a set is a 
# subset of another se

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 setObj2 <= setObj1
    puts "setObj2 is the subset of setObj1.";
else
    puts "setObj2 is not the subset of setObj1.";
end

Output:

setObj2 is the subset of setObj1.

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 setObj2 is the subset of setObj1 using the "<=" operator and printed the appropriate message.
