The pseudocode for a bank account supporting concurrent access. Assume that Lock is a valid locking class, although it is not in Java. Since Lock is not reentrant, the code below is broken. Assuming Lock is not reentrant, Please help me to provide a detailed example where the withdraw method would block forever. Refer to locks using the commented operation number. class BankAccount { private int balance = 0; private Lock lk = new Lock(); int getBalance() { lk. acquire(); // Operation 1 int ans = balance; lk. release(); // Operation 2 return ans; } void setBalance(int x) { lk. acquire(); // Operation 3 balance = x; lk. release(); // Operation 4 } void withdraw(int amount) { lk. acquire(); // Operation 5 int b = getBalance(); if (amount > b) { lk. release(); // Operation 6 throw new (); } setBalance(b - amount); lk. release(); // Operation 7 }}

3. ranga ramasesh is the operations manager for a firm that is trying to decide which one of four countries it should research for possible outsourcing providers. the first step is to select a country based on cultural risk factors, which are critical to eventual business success with the provider. ranga has reviewed outsourcing provider directories and found that the four countries in the table that follows have an ample number of providers from which they can choose. to aid in the country selection step, he has enlisted the aid of a cultural expert, john wang, who has provided ratings of the various criteria in the table. the resulting ratings are on a 1 to 10 scale, where 1 is a low risk and 10 is a high risk. john has also determined six criteria weightins: trust, with a weight of 0.3; quality, with 0.2; religious, with 0.1; individualism, with 0.2; time, with 0.1; and uncertainity, with 0.1. using the factor-rating method, which country should ranga select? why?
