Verify the validity of the following correctness statement by adding all the intermediate assertions, that is, give the proof tableau. All the variables are of type int. Clearly state any mathematical facts used. The mathematical facts can be included as comments in the tableau. ASSERT (x < 1 && y <= 1) y = x + y; x = y-X; ASSERT (x==2 || x + y < 3)

For the 8 Java statements below, identify each of the following statements as legal or illegal, and whether legal or not, state whether it represents a "narrowing" or "widening" conversion, or neither. Don't forget to identify the last statement at the very bottom, Member m = new BoardMember();, as legal or illegal and widening or narrowing conversion.

Hr, Min, Sec Constructors to handle: default, (4, 15, 6), (1,30), (14), (clock1) Overload <> ++,, >=, ==, != Get and Set methods. Write a tester program that creates 2 clocks(Input from the user). The first clock will represent the real time and one will represent your alarm clock. Do a loop that will continue to add 1 second to the current time and stop when it reaches the alarm clock time. Display the time each second on the screen. You can use system("CLS"); to clear the screen each time so it looks like it is overwriting the current time. #include void main() { system("cls"); }
This challenge is based on the classic videogame "Snake". Assume the game screen is an n * n square, and the snake starts the game with length 1 (i.e. just the head) positioned on the top left corner. For example, if n = 7 the game looks something like this: BEGINNING In this version of the game, the length of the snake doubles each time it eats food (e.g. if the length is 4, after eating it becomes 8). Create a function that takes the siden of the game screen and returns the number of times the snake can eat before it runs out of space in the game screen. Examples FIRST MOVE snakefill (3) snakefill (6) - 5 snakefill (24) → 9 3
Below are some statements; the domain of each is the set of all integers. For symbolic statements, thenegation symbol (¬) must not apear in your answer. For English statements, don’t use “It is not the casethat” or just the word “not” to form the negation.For each one, state whether the statement is TRUE, FALSE, or CAN’T BE DETERMINED. For all that onesthat are TRUE or FALSE, state the negation:1.∃n(nis even)2.∀a∀b(3a≥2b)3.∀a∃b(ab= 1)
