Ordered Printing

Suppose there are three threads t1, t2 and t3. t1 prints First, t2 prints Second and t3 prints Third. The code for the class is as follows:

class OrderedPrinting 
 
    def printFirst() 
       puts "First" 
    end
 
    def printSecond() 
       puts "Second"
    end
 
    def printThird() 
       puts "Third"
     
end

Thread t1 calls printFirst(), thread t2 calls printSecond(), and thread t3 calls printThird(). The threads can run in any order. You have to synchronize the threads so that the functions printFirst(), printSecond() and printThird() are executed in order.

The workflow of the program is shown below: ...
