Eda case study on insurance data

Visualise the data and write down the important points

Ninja started his new job as a manager in Railways Control Room. His task is to maintain the records of passengers traveling from one place to another. His task is to design a class that performs the following operations:

‘RAILWAY_SYSTEM’() is a function that initializes your data structures.

‘CHECK_IN’( ‘PASS_ID’,’ STATION’, TIME) represents that passenger with passenger ID ‘PASS_ID’ checks in at the station named ‘STATION’ at time ‘TIME’.

 A customer can only be checked into one place at a time.

‘CHECK_OUT’( ‘PASS_ID’,’ STATION’, TIME) represents that passenger with passenger ID ‘PASS_ID’ checks out at the station named ‘STATION’ at time ‘TIME’.

‘GET_AVERAGE_TIME(SOURCE, DEST) returns the average time it takes to travel from SOURCE to DEST.

The average time is computed from all the previous traveling times from SOURCE to DEST  that happened directly, meaning a check-in at SOURCE followed by a check out from DEST.

For Example

If the functions calls are as follows:
CHECK_IN(1,‘Delhi’,10)
CHECK_OUT(1,‘Noida’,20)
GET_AVERAGE(‘Delhi’,’ Noida’)
CHECK_IN(5,‘Delhi’,12)
CHECK_OUT(5,‘Noida’,17)
GET_AVERAGE(‘Delhi’,’ Noida’)

So, the answers for the GET_AVERAGE calls will be 10 and 7.5 respectively.
For the first call, there is only one trip between Delhi and Noida, so the average is 10.
For the second call, there are two between these stations, so the average is (10+5)/2 = 7.5
