28. Which statement of the following is the most appropriate? Group of answer choices The size of a dynamic array needs to be determined at compilation. Such behavior, determined at compile time, is called dynamic behavior. Dynamic behavior is more flexible than decisions that are made at run time (i.e., static behavior). The size of a dynamic array does not need to be determined until a program is running. Such behavior, determined at run time, is called dynamic behavior.

JAVA 8.13 LAB: Movie show time display Write a program that reads movie data from a csv (comma separated values) file and output the data in a formatted table. The program first reads the name of the CSV file from the user. The program then reads the csv file and outputs the contents according to the following requirements: Each row contains the title, rating, and all showtimes of a unique movie. A space is placed before and after each vertical separator (|) in each row. Column 1 displays the movie titles and is left justified with a minimum of 44 characters. If the movie title has more than 44 characters, output the first 44 characters only. Column 2 displays the movie ratings and is right justified with a minimum of 5 characters. Column 3 displays all the showtimes of the same movie, separated by a space. Each row of the csv file contains the showtime, title, and rating of a movie. Assume data of the same movie are grouped in consecutive rows. Ex: If the input of the program…

Write a program that accepts two four-digit binary numbers, converts them to decimal values, adds them together, and prints both the decimal values and the result of the addition. Requirements: Functionality. (80pts) No Syntax Errors. (80pts*) *Code that cannot be compiled due to syntax errors is nonfunctional code and will receive no points for this entire section. Clear and Easy-To-Use Interface. (10pts) Users should easily understand what the program does and how to use it. Users should be prompted for input and should be able to enter data easily. Users should be presented with output after major functions, operations, or calculations. All the above must apply for full credit. Users must be able to enter a 4-bit binary number in some way. (10pts) No error checking is needed here and you may assume that users will only enter 0’s and 1’s, and they will only enter 4 bits. Binary to Decimal Conversion (50pts) You may assume that users will only give numbers that add up to…
C 8 PDF assignment1.pdf File C:/Users/sebas/Downloads/HW1 Handout/handout/assignment1.pdf Q of 8 X New Tab x + col. + {B | An | (T) 1. A cell that has fewer than two live neighbors dies (because of loneliness) 2. A cell that has more than 3 live neighbors dies (because of over-crowding) 3. A cell that is dead and has exactly 3 live neighbors comes to life 4. All other cells maintain their state V Game of Life (Finally) So, for this step, change your life function so that it calls a new function named updateNextLife( oldB, newB ) in place of updateReversed, above. Then, implement the updateNextLife( oldB, newB ) function so that it sets each cell in the new data according to the updating rules based on the old generation, oldB: DI As suggested in updateReversed, always keep all of the outer-edge cells empty. This is simply a matter of limiting your loops to an appropriate range. However, it greatly simplifies the four update rules, above, because it means that you will only update the…
Create the following functions makeBoard Accepts two parameters, integers mm and nn, and creates an mm x nn numpy array of zeros Returns the created array makeMove Accepts two parameters, a 2D array (such as created by makeBoard), and an integer xx Checks if the value at position xx in the array is 0. If it is, changes it to 1 and returns True If it isn't, does not change it and returns False Position xx in the array is given by reading the array top-down and left-to right. A simple 2x3 array is seen below with each value representing its position You may assume without checking that the value of xx provided is valid, that is it is within the array. Hint: Arrays have a property you can use to determine their shape. Hint: This function may (and indeed should) contain if statements, but no loops. Sample array with positions: [[0 1 2][ 3 4 5]] For testing purposes, you may copy the function provided here into your code def playGame(mm,nn): board = makeBoard(mm,nn)…
