Given main(), build a struct called BankAccount that manages checking and savings accounts. The struct has three data members: a customer name (string), the customer's savings account balance (double), and the customer's checking account balance (double). Assume customer name has a maximum length of 20.
Given the following code entered in the IDL shell: >>> names = ["Dancer", "Prancer", "Vixen", "Rudy"] >>> for each in names: each = each + Deer" print(each) Dancer Deer Prancer Deer Vixen Deer Rudy Deer >>> names ['Dancer', 'Prancer', 'Vixen', 'Rudy'] The names of the reindeer in our names list are not altered even though we are re-assigning a new value inside of the for loop. The original list is not altered because (select the BEST answer): O Lists are immutable so the values cannot be changed O The for-each style of iteration we used is pass-by-REFERENCE (or position) so the value does not change in the original list O The for-each style of iteration we used is pass-by-VALUE so the value does not change in the original list O We are using the IDLE shell. If this was a program file, the names would change

You have recently joined a start-up that focuses on selling domain names. You have assigned a task to calculate the surcharge imposed on registering the domain name. The input starts with a line containing 2 space separated integers m & n followed by a blank line. m is the number of already registered domain names. n is the list of names that a customer wishes to register (1
Given the following function header: def second_largest(1st: list[int]) -> int: Given a list of integers, return the second largest item in the list without modifying . Precondition: len(1st) >= 2 and given the following list of test cases (labelled TEST 1 through TEST 6): TEST 1: second_largest ([1, 2]) TEST 2: second_largest([e, 3]) TEST 3: second_largest([2, 1])| TEST 4: second_largest ([1, 3, 0]) TEST 5: second_largest([1, 3, 2]) TEST 6: second_largest([3, 1, 0])] Identify any tests which duplicate cases tested earlier in the list. For example, if TEST 3 duplicates something TEST 1 or TEST 2 have done, then select TEST 3 (as it has a duplicate test case). O TEST 1 O TEST 2 O TEST 3 O TEST 4 O TEST 5 O TEST 6
