Which of the following statments best characterizes the tradeoff between using @ to add an item to the end of a list vs using :: to add an item to the beginning of the list? O @ enables you to append, which is impossible with :, but requires copying the whole list. O Either can be used to append, but you need to remember the ) to build a list around the element when using @ :: is faster and more efficient at adding items both to the beginning and ends of lists directly. For example, L ::3 is more efficient than L@ [3] O Both using @ to add an item to the end of the list and : to add an item to the beginning of the list are equally efficient.

python LAB: Subtracting list elements from max When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This can be done by normalizing to values between 0 and 1, or throwing away outliers. Write a program that adjusts a list of values by subtracting each value from the maximum value in the list. The input begins with an integer indicating the number of integers that follow.
| Which data structure to use? Suppose you need to store a list of elements, if the number of elements in the program is fixed, what data structure should you use? (array, ArrayList, or LinkedList) If you have to add or delete the elements at the beginning of a list, should you use ArrayList or LinkedList? If most of operations on a list involve retrieving an element at a given index, should you use ArrayList or LinkedList?
SA1: What is the maximum number of values linear search must check to find a value in a list with 2 billion values? SA2: What is the maximum number of values binary search must check to find a value in a list with 2 billion values?
4 ete t of With the following lists: list1 = [x + y for x in ['a', 'b', 'c'] for y in ['1', '2', '3']] list2 = [[x + y for x in ['a', 'b', 'c']] for y in ['1', '2', '3']] which option is true? Select one: A. len(list1)> len(list2) B. 'a1' is an element (or subelement) for list1 whereas '1a' is for list2 C. list1 and list2 will error because numbers and letters cannot be added. D. Both A and B are true.
What does the following error message normally mean? IndexError: list index out of range Select one: а. This error normally indicates that you have tried to access an element of a list that doesn't exist. O b. This error normally means that you have used the range() function incorrectly. С. This error normally means that you have used a list where you should have used a tuple. d. This error normally means that you used too many lines of code in your program.

List operations: Add something to the end of a list, remove something from the end of a list, add something/remove something from the middle of the list, get/set values by indexing into the list. How long does each of these operations take for each kind of list? Find the size of a list, check if it is empty Repeatedly remove the last value in a list until the list is empty Print out each element of the list Swap every pair of values in the list Which data structure is best for • random access • insertion/removal at a cursor? when a cursor needs to move forward and backward? • insertion/removal at the front? • insertion removal at the end?
PYTHON I need help writing this code # Argument a list consisting of "Drink", and "Popcorn" Strings. # Destructively Remove all "Popcorn" elements from orders. # This means that the caller won't see any "Popcorn" in their # original list anymore It will still contain 'Drink' strings. # Return a NEW list containing all of the removed popcorn strings. #3 # Example: orders: ["Drink", "Popcorn", "Drink', 'Popcorn'] # orders after your function mutates it: ['Drink', 'Drink'] # Returned list: ['Popcorn', 'Popcorn'] 23 # Hint: You can use del operator or construct a new list and use orders[:] = # To mutate the caller's original list into your new edited list. #3 # Hint: This function effectively communicates 2 lists back to the function # caller. The mutations to the argument list, and the returned list. 23 def drinksAndPopCorn(orders): pass

Assume the following method is in class TestSLList (a method outside the SingleLinked List class). public static void test5Question(SingleLinkedList list, int item) { while( list.contains(item) ) list.remove((Integer) item); } a. The method removes the last occurrence of item from "list". b. The method removes all occurrences of item from "1ist". O. The method removes the element at location item from "list". Od. The method removes the first occurrence of item from "list".
