Create a BankAccount class with the following properties: Account Number (string) Account Holder Name (string) Balance (double) Account Type (enum: Savings, Current) Create the following methods in the BankAccount class: Deposit(double amount): Method to deposit money into the account Withdraw(double amount): Method to withdraw money from the account CheckBalance(): Method to check the current balance of the account Create a Bank class with the following properties: List of bank accounts (List) Create the following methods in the Bank class: AddAccount(BankAccount account): Method to add a new bank account to the list of accounts RemoveAccount(string accountNumber): Method to remove an existing bank account from the list of accounts SearchAccount(string accountNumber): Method to search for an existing bank account and return the account details Create a Program class with the Main method, and implement the following functionality: Create an instance of the Bank class Add at least 3 bank accounts to the list of accounts Search for an existing account and display the account details Deposit an amount into one of the accounts Withdraw an amount from one of the accounts Search for the account again and display the updated account details Remove one of the accounts Note: To test the functionality of the BankAccount and Bank classes you can create multiple instances of the classes and test the methods Add appropriate input validation (remember: an example of input validation would be typing a letter when the program is asking for a number, and instead of the program crashing, it simply disregards the letter and asks for a correct value) wherever necessary to make sure the methods are working correctly. Add some comments to the code to explain what each block of code is doing. Add some test cases to test the implemented functionality
