Question 2 [Points 4] Let us try to solve the above race condition in the banking application using semaphores with wait () and signal() operations. Assume that the three variables that are to be protected through the semaphores are: balance, withdrawals, and deposits. Assume that all these variables are initialized to 0 . The three functions of interest are: deposit_money, withdraw_money, find_balance. For simplicity, assume that there is only one account that we need to deal with. Write pseudocode using semaphore ACCT to implement the three functions. (Code can be at the same level of detail as in the book examples.) Question 3 [Points 4] Answer question 2 above using a monitor instead of a semaphore
