1. There are local vars for counting left, right hosts.

2. Initially left_count = 0, right_count = 0.

3. Client sends 1 to left and right hosts.
   This way hosts learn about each other.
   
4. Each server is waiting for a message from left,right. 

5. When a server gets a message from left:

    5.1. Server compares left_count from getting_count(count from message).
    
    5.2. If getting_count > left_count than left_count = getting_count.
        This way server understands that there are more left hosts.
        
    5.3. Server sends left_count increasing by 1 right down the chain.
    
6. When a server gets a message from right it compares etc.

7. Servers are closed by timeout when they will no longer recieve messages.

8. Total number of computers in chain will be (left_count + right_count + 1).
