Printing FooBar n Times

Suppose there are two threads t1 and t2. t1 prints Foo and t2 prints Bar. You are required to write a program which takes a user input n. Then the two threads print Foo and Bar alternately n number of times. The code for the class is as follows:

class PrintFooBar 
    
    def PrintFoo()
        for i in 1..n do
        print "Foo"    
        end  
    end

        for i in 1..n do      
        print "Bar"    
        end  
    end
end

The two threads will run sequentially. You have ...
