Python:

Create two Binary Tree class methods that can return the maximum value within a Binary Tree and the minimum value within a Binary Tree.

Test the methods in your code

Example syntax to call these methods:

MyTree.Max()

MyTree.Min()

How to make a flow chart out of this???

To compute the rates you have the following established: 1. Regular service - $6.00 plus first 50 minutes free. Charges for over 50 minutes are $0.20 per minute. 2. Premium service - $15.00 plus: a. For calls made from 6:00am to 6:00pm, the first 75 minutes are free; charges for over 75 minutes are $0.10 per minute. b. For calls made from 6:00pm to 6:00am, the first 100 minutes are free; charges for over 100 minutes are $0.05 per minutes. Task Your task at the moment is to calculate and print out the bill for your customers. Your program should: 1. prompt the user to enter an account number, 2. a service code (type char), a. A service code of r or R means regular service b. A service code of p or P means premium service c. Treat any other character as an error 3. the number of minutes the service was used. Your program should output the account number, type of service, number of minutes the telephone service was used, and the amount due from the user. For the premium service, the customer may be using the service during the day and the night. Therefore, to calculate the bill, you must ask the user to input the number of minutes the service was used during the day and the number of minutes the service was used during the night. Concepts to follow: 1. Assign values to all constant variables that are associated with charges and number of minutes provided in the problem description. 2. The only information the user enters are: account number, type of service, minutes used, and day/night time minutes used based on the plan they have. 3. Remember you are dealing with money therefore should only have 2 decimal places. 4. You must use both a switch statement AND if/else, if/else if’s, or if’s as you see fit. 5. Keep in mind to check for input validation. If validation is incorrect you should have an error message and “kill” your program. 6. Do not use loops

Lab 7 - 2D Arrays (C++) In main, declare and fill a 2D array with one hundred rows and fifty columns. Iterate through each element and assign it a random value between -72 and 75 inclusive. Have your random number seed be 25. Create functions that do the following: 1. A function called “sum” that returns the sum of all the elements in your 2D Array. 2. A function called “average” that return the average value of the elements in your 2D array. 3. A function called “column_average” that returns the average of a specified column in your 2D array. 4. A function called “row_average” that returns the average of a specified row in your 2D array. 5. A function called “sort_row” that sorts a specified row in your 2D array. 6. A function called "search" that does a linear search on a user specified row and returns the columns index where it was found. If it wasn't found, return -1. Make sure you pass in the value to be search for.. Create a menu system that enables the user to call each of the above functions. For 3 and 4 allow the user to enter the column or row they wish to see the averages of. For 5, allow the user to specify the row to be sorted and ask them if they would like to see the min and max element of that row. The user should be able to enter ‘Y’, ‘y’, ‘N’, or ‘n’. Make sure to validate all user input. If they entered an invalid value, don’t ask them for a valid input and just pass zero to your function. For 6, ask the user for the row and value (space separated) to be searched.

Write in Python.

come up with a programming task for which you will write your own program. It should be a purposeful and non-trivial program, bigger than any programming assignment. But it should not be something too ambitious that you may not end up finishing by the deadline. The program must not be something available on the Internet or in a book. The program must satisfy the following five requirements:

1. It must define and appropriately use at least one class.
2. It must use at least two meaningful functions besides main function and the class methods.
3. Its input and output must be through files (some user input, or output to screen is ok in addition, if needed)
4. It must use at least one list or one dictionary.
5. The program must be well documented with module documentation (three double-quote comments) for functions and classes as well as comments at appropriate places in the program.

Please feel free to contact the instructor if any help is needed at any stage of the project.

Submission:

1. Submit your .py program file(s)
2. Submit sample input/output file as needed
3. Submit a plain text file called README.txt that clearly explains:
   • The programming task and its specifications
   • Your programming design (e.g. what part of the program does what)
   • How to run your program

1) Write a denotational semantics for do-while loop

What is the output of the StackQueueMystery algorithm (below) when we have enqueued 1, 2, 5, 6, 3, 7, 4, 10, 8, 9 on q and pushed 8, 6, 9, 7, 10, 5, 4, 3, 2, 1 on stk (in that order) before calling this algorithm. Show your work.

StackQueueMystery:

Input: stk: stack with integers 1-n

Input: q: queue with integers 1-n

Input: n: size and range of stk and q

Pseudocode:

count = 0

while stk and q are not empty:

{

    x = x0 = stk.pop()

    y = y0 = q.dequeue()

    while x != y0 and stk is not empty

        x = stk.pop()

    while y != x0 and q is not empty

        y = q.dequeue()

    count = count + 1

}

return count

If varible counter contains an integer, then write an augmented assignment operation to decrement it by 1. A “count-controlled” for loop using the xrange function to average the scores for a class is given below and in the file PartD_average_with_for.py:

# Calculates the average score using a counter-controlled for-loop numberOfScores = input("Enter the number of scores to average: ")

total = 0.0;

for counter in xrange(numberOfScores):

score = input("Enter score #" + str(counter+1) + ": ") total = total + score

if numberOfScores > 0:

print "The average score is", total / numberOfScores

Hi, i need to generate into groups the array.For example:

([ 'a', 'b', 'c', 'd' ], 2)=>[ [ 'a', 'b' ], [ 'c', 'd' ] ]

([ { id: 5 }, { id: 10 }, { id: 20 } ], 2)=>. ([ [ { id: 5 }, { id: 10 } ], [ { id: 20 } ] ])

Question 14: Find the running time function, T(n), of the program below.

def prob14(L):

    if len(L) <= 1:

        return 0

    output = 0

    for x in L:

        for y in L:

            output += x*y

    for x in L:

        output += x

    left = L[ 0 : len(L)//2 ]

    right = L[ len(L)//2 : len(L) ]

    return output + prob15(left) + prob15(right)
