for i - x to x+3 do v - i for j - 1 to y do v - v*i end for print v end for [NOTE:The statement i + X replaces the old value of the variable i with the result of evaluating the expression x. For example, if i initially contains 7 then the statement i +x+1 results in i containing 8.] Which of the following cannot be produced by the instructions for any value of x?

ASuppose that x and y are variable names that already refer to Boolean values.Write an expression (not a statement!) that evaluates to True iff at least oneof the variables is False.B.Suppose that x, y, and z are variable names that already refer to Boolean values.Write an expression (not a statement!) that evaluates to True iffat least two of the three variables (x, y, z) are True.C. Consider the following function headers and type contracts:def aragorn(x: int, y: str, z: float) -> str:def gandalf(x: list) -> list:def elrond(x: list, y: bool) -> bool:If the following code runs without errors, what is a header and type contractfor treebeard?a = aragorn(11, 'good', 2.0)b = treebeard(5, gandalf([1, 2, 3]), a)print(elrond(gandalf([4, 5]), b))Write the header and type contract for treebeard.

[Python Language]   A common back-of-the-envelope technique for estimating a runner’s marathon time is to take their best half-marathon time, multiply by two and add ten minutes. This works pretty well unless the marathon course is hilly.If it is hilly, we add an extra 20 minutes to the estimate. Write a program that takes two lines of input: a float giving the half- marathon time in minutes and an integer indicating whether the marathon course is hilly(1) or not (0). It prints a float giving the estimated number of minutes the runner will take to run the full marathon. Write your pro- gram in a file named marathon.py.

Could you make sure the code is correct. Please read the instructions carefully and the example runs. Thanks.

Practicing Loops. Einstein Private Elementary school has three classes in each of its 9 grades. 27 classes in total.  It has kindergarten (grade 0) though 8th grade.   The school allows parents to pay tuition over the nine-month school year.  Tuition for kindergarten is $90 dollars every month.  Tuition for the other grades is $50 times the grade level every month.  (1st grade is $50 a month, second grade is $100 a month, etc.) Design a programming solution that outputs nine tuition payment bills for each of the 27 classrooms.  Each bill must contain the grade number (0 through 8), the classroom number (1 through 3), the month (1 through 9) and the amount of the tuition due. Your output should look something like: Grade Classroom Month Tuition   0             1               1        90   0             1               2        90   0             1               3        90   0             1               4        90   ...   8             3               7      400   8             3…

write in python

Write the syntax for a do/while loop that executes as long as a character variable has a value of either “y” or “Y”. (Assume the character variable is already declared, and give it a valid identifier name of your choosing, given that its purpose is to store the user’s response to the question “do you wish to input another set of data?”. You do not need to include any statements in the curly brackets for the loop.) (** How do I do this in c**)

Describe what the following code is doing (the outcome), by annotating each line of code and giving an overall description of the function of the code. Also, perform a desk check (trace) of the program. Must show multiple iterations of the program loops in the desk check (trace).
