Skill set for this LAB:

• Understand and implement the Program Development Cycle
• Use Simple Functions
• LOOP WHILE, LOOP FOR
• Use Top-Down Design
• Use variables and assignment statements
• Use input and print functions
• Use basic arithmetic operations
• Save, run and submit programs
• Testing programs
• Writing Lab reports

• Python Programming Assignment

  In all programs:

  • YOU MUST TO WRITE INFORMATIVE COMMENTS!
  • You MUST use Top-Down Design
  • Each subtask MUST be a separate function
  • You MUST have function MAIN in your program.

    Problem 1 (50 points) : Write the following functions:

    • Function sumNeg that has one parameter - the number of input integers. The function inputs integers, and finds and RETURNs the sum of the negative inputs. If there are no negative inputs, the function returns 0. USE LOOP FOR in this function.
    • Function average that has NO parameters. The function inputs the series of positive integers. The first zero or negative terminates the input. The function finds and RETURNs the average of the ODD input numbers which are also divisible by 7. If there are no such inputs, the function returns -1. In this function you can only use LOOP WHILE.
    • Function menu that has one parameter - choice. The function performs the following: if the choice is 1, user is asked to enter the number of inputs and the function sumNeg is called. If the choice is 2, function average is called. For all other choices, function outputs error message.
    • Write main function that reads one integer - user's choice and call function menu.

    Problem 2 (30 points): Write a function maximum that has three parameters. The function returns the maximal value among its parameters. Write a function processMax that reads 10 integers and finds and returns the maximal between three values: number of positive inputs, number of negative inputs and number of zeros. Use function maximun to find a maximal value between these 3 values. Write a program that tests your functions.

    Problem 3 (20 points) : In this program you need to implement the simplified version of the new score system in the Figure Skating competition. Description of the simplified version: There are 12 judges that are present. First step: all 12 judges submit their scores. Second step: the highest and lowest score are thrown out from the 12 submitted grades. Third step: the remaining 10 scores are averaged. Write a program that reads 12 scores submitted by 12 judges for the specific event and calculates the final score according to the rules written above. Each input score is an integer number between 0 and 100. You can assume that the input is valid. You can write everything in main.

    Example:
    Input: 12 49 100 98 99 16 13 100 99 12 99 100
    Output:
    The final score is: 68.5
