 ### Exercise Problem
 
 - [Problem 1] Fix the bug in AbstractBankServer state machine and run the P Checker again on the test case to ensure that there are no more bugs in the models.
-- [Problem 2] Extend the ClientServer example with support for depositing money into the bank. This would require implementing events `eDepositReq` and `eDepositResp` which are used to interact between the client and server machine. The Client machine should be updated to deposit money into the account when the balance is low and the BankServer machine implementation would have to be updated to support depositing money into the bank account. After implementing the deposit feature, run the test-cases again to check if the system still satisfies the desired specifications.

The Client machine should be updated to deposit money into the account when the balance is low, the BankServer machine implementation would have to be updated to support depositing money into the bank account and finally safety and liveness specifications needs to be updated take disposit events into account.

 !!! success "What did we learn through this example?"
     We explored writing P state machines, safety and liveness specifications as P monitors, writing multiple model checking scenarios to check the correctness of a P program, and finally, replacing complex components in P with their abstractions using P's module system.
