Write a program that has the "account_balance" as a global variable and the function "add_balance(amount)". The function reads the current balance value, adds an amount to it (which is entered by the user) and writes the new value to the balance variable. After that, create 2 threads which will invoke the add_balance(amount) function and add different values. Run the program and make sure that the data is consistent (Use a proper lock on the variable).
