- The National Bank of Erehwon handles money and maintains bank accounts on behalf of clients. A client is a person who does business with the bank. A client may have any number of accounts, and an account may belong to multiple clients (e.g., spouses, business partners). The client record is used for identification and contact data. For each account, the bank maintains the current balance on hand. Clients are identified by a five digit number starting with 10001. Accounts are identified by a seven digit number starting with 1000001. When an account is first opened, its balance is set to zero. During the course of day-to-day business, Erehwon Bank applies transactions to accounts, including deposits, withdrawals, bill payments, and debit purchases or returns. For each transaction, the date and time, amount, and account are recorded, along with reference data applicable to that type of transaction: Deposits and withdrawals require the branch number to be recorded.…arrow_forwardPlease type thank you! Tasks: 1. Write a python program that implements the estimation of Pi through a Monte Calo simulation. 1) How many iterations do you need to run? make a case for when it is a good approximation of Pi. 2) Suggest a method that would accelerate the approximation of Pi. You may either suggest a method that would accelerate the approximation of Pi than the method you described in b, or you may describe two methods and explain which one can accelerate the approximation of Pi than the other one.arrow_forwardTASK 8. Repeat TASKs 4-7. Change Summation Integers problem to Finding the minimumproblem. Make sure you properly wrote/updated all text messages, method names,and math calculations.Hint: You can use java.lang.Math.min() method.Example: System.out.printf("The min of the integers %4d and %4d and %4dis %7d\n", a, b, c, MinTest(a, b, c));Submit the source code files (.java files) and the console output screenshotsarrow_forward
