def update_grid(grid: List [List [str]], w: int, h: int, px: int, py: int,dx: int, dy: int) -> Optional [Tuple [int, int]]:Given the player's current position as px and py,and the directional changes in dxand dy, update the given grid to change the player'sx-coordinate by dx, and their y-coordinate by dy.More information:Use the given w and h (representing the grid's widthand height) to figure out whether or not the move is valid.If the move is not valid (that is, if it is outsideof the grid's boundaries), then NO change occurs to the grid.The grid stays the same, and nothing is returned.If the move IS possible, then the grid is updatedby adding dx to the player's x-coordinate,and adding dy to the player's y-coordinate.The new position in the grid is changed to the playericon ' (x)', and the old position the player used to be inis changed to an empty space 'O'. The new x- and y coordinatesof the player is returned as a tuple.This function does NOT create or return a new grid.It modifies the "grid" 1ist that is passed into it directly.>>> L = [[' (x)''Q'1, IO', (0)'1, lO', 'O'1]>>> update_grid (L, 2, 3, 0, 0, 1, 0)(1, 0)>>> L[[O', '(x)'1, ĽO', '(0)'1, IO', 'O'1][l' (x)', 'O'1, [O', '(0)'1, I'O', 'O'1]>>> L =(0, 1)>>> L[[O', 'O'1, I' (x)', ' (o)'1, IO', 'O'1][[' (x)', 'O'], I'O', '(0)'], IO', 'O']]>>> L =>>> print (update_grid (L, 2, 3, 0, 0, -1, 0))None>>> L[[' (x)', ')'1, Ľ'O', '(0)'1, IO', 'O'1] def make_grid (w: int, h: int, player_coord: Tuple [int, int],gold coord: Tuple [int, int]) -> List [List[str]]:Given two integers width w and height h, create a listof lists to represent a grid of the given width and height.The coordinates for the player and the goldis also given as two two-element tuples.

You are going to implement a program that creates an unsorted list by using a linked list implemented by yourself. NOT allowed to use LinkedList class or any other classes that offers list functions. It is REQUIRED to use an ItemType class and a NodeType struct to solve this homework. The “data.txt” file has three lines of data 100, 110, 120, 130, 140, 150, 160 100, 130, 160 1@0, 2@3, 3@END You need to 1. create an empty unsorted list 2. add the numbers from the first line to list using putItem() function. Then print all the current keys to command line in one line using printAll(). 3. delete the numbers given by the second line in the list by using deleteItem() function. Then print all the current keys to command line in one line using printAll().. 4. putItem () the numbers in the third line of the data file to the corresponding location in the list. For example, 1@0 means adding number 1 at position 0 of the list. Then print all the current keys to command line in one…

| 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?
