Instructions

Run coordinator first 
eg: python coordinator.py 8888

Then run servers
eg: python server.py localhost:8888 8003 server3 server3.log
it will create a log named server3.log in the same directory

the port numbers should be different for all 3 servers
logs should be named different as well
eg
server1 : python server.py localhost:8888 8001 server1 server1.log
server2 : python server.py localhost:8888 8002 server2 server2.log
server3 : python server.py localhost:8888 8003 server3 server3.log

then run any number of clients and use menu to make queries
eg: python client.py localhost:8888 client


to check resync open log on any server and remove some lines 
eg:
1 101 40
2 101 10
3 101 10
4 101 20
5 101 30
6 103 40
7 103 40
8 103 40
9 103 40
10 101 30 

to 

1 101 40
2 101 10
3 101 10
4 101 20


it is important to keep a blank line at the end of the log or it wont work properly
eg
'''1 101 40
2 101 10
3 101 10
4 101 20
5 101 30
6 103 40
7 103 40
8 103 40
9 103 40
10 101 30

'''

save log after changing and on the same server terminal press Ctrl+C
Then reload the log it should be updated
