Textbook Question

Chapter 11, Problem 11.9PE

(Largest rows and columns) Write a program that randomly fills in 0s and 1s into an n-by-n matrix, prints the matrix, and finds the rows and columns with the most 1s. (Hint: Use two ArrayLists to store the row and column indices with the most 1s.) Here is a sample run of the program:

When the FCC added Color Television to the Industry Standards, they went with the system developed in the 1940s by Peter Goldman for CBS. Question 15 options: True False Part of the reason that many critics disliked 1950s gameshows was the fact that gameshows offered one of the few opportunities to see unscripted interactions with "real" (average/non-famous) people on television. Question 16 options: True False The Andy Griffith Show is an example of the "rural revival" shows that become enormously popular on 1960s American television. Question 19 options: True False During the Network Era, the hours before primetime each day were exclusively devoted to locally-produced programming, not programming dictated by an affiliate station's parent network. Question 20 options: True False

Although color television was not added to the industry standard until 1956, CBS had been broadcasting selected special events in color as early as 1950. Question 1 options: True False Two key factors in creating the Network Era of American television were the FCC licensing freeze and ______________. Question 4 options: The Quiz Show Scandals Habitual Viewing Operation Frontal Lobes Drop-In Viewing Least Objectionable Programming was designed to embrace the public service-oriented vision of using television to elevate mass culture and enrich viewers. Question 6 options: True False By the end of the 1950s, all three remaining networks (NBC, CBS, & ABC) were broadcasting their entire nightly programming schedule in full color. Question 9 options: True False

7. See the code below and solve the following. public class Test { public static void main(String[] args) { int result = 0; } result = fn(2,3); System.out.println("The result is: + result); // fn(x, 1) = x // fn(x, y) = fn(x, y-1) + 2, when y>1 public static int fn(int x, int y) { if (x <= 1) return x; else return fn(x, y-1) + 2; } } 7-1. This program has a bug that leads to infinite recursion. Modify fn(int x, int y) method to fix the problem. (2 point) 7-2. Manually trace the recursive call, fn(2,3) and show the output (step by step). (2 point) 7-3. Can you identify the Base Case in recursive method fn(int x, int y)? (1 point)
