Use the pseudocode methods below to answer the questions in C++. FIRST METHOD: COMMENT parameters should be integers METHOD largestValue(parameters: num1, num2) BEGIN IF(num1 >= num2) THEN result ← num1 ELSE result ← num2 ENDIF END largestValue SECOND METHOD: COMMENT parameters should be doubles METHOD largestValue(parameters: num1, num2) BEGIN IF(num1 >= num2) THEN result ← num1 ELSE result ← num2 ENDIF RETURN result END largestValue THIRD METHOD: COMMENT parameters should be integers METHOD largestValue(parameters: num1, num2, num3) BEGIN IF(num1 >= num2 AND num1 >= num3) THEN result ← num1 ELSE IF (num2 >= num3) THEN result ← num2 ELSE result ← num3 ENDIF RETURN result END largestValue Given the pseudocode methods above and on the previous page, which method corresponds to each of the method calls specified?

Problem Statement: The mathematician Conway imagined a game, called game of life, which considered cells that are susceptible to reproduce, disappear, or survive when they obey certain rules. These cells are represented by elements on a grid of squares, where a grid has an arbitrary size. Thus, each cell (except those on the boundaries of the grid) is surrounded by eight squares that contain other cells. The rules are stated as follows: 1. Survival: Each cell that has two or three adjacent cells survives until the next generation.2. Death: Each cell that has at least four adjacent cells disappears (or dies) by overpopulation. Also, each cell that has at most one adjacent cell dies by isolation.3. Birth: Each empty square (i.e., dead cell) that is adjacent to exactly three cells gives birthto a new cell for the next generation.It is worth noting that all births and deaths occur at the same time during a generation. Write a program that simulates this game and displays all successive…

Please answer 6 and 7 as they are associated altogether. 6. The FixProgram.java below has some errors.a. Fix the errors so that the program successfully compiles and runs. class FixProgram{ public static void main(String[] args) { System.out.println('Hello World!') }} 7. Change the SampleProgram.java program below.a. So that it displays Programming is fun! Instead of Hello World! class SampleProgram{ public static void main(String[] args) { System.out.println("Hello World!"); }}
