Post #1: Briefly respond to the questions below by Tuesday.Post a new metsage in narrative form (i.e. no bullet points) that addresses the following questions:• In your own words, explain the concept of variable scope. Include one or more code fragments that you write for this discussion post to help illustrate your case. Clearly markas appropriate any code fragments as either "script" code or "function" code, and use comments in your code to note the locality of each variable at least the first time thevariable appears in the script or function. If a variable is lọcal in scope, be sure to notate what the variable is local to (i.e. the script, a particular function, etc.). Your code forthis discussion post should include at least two different local variables, and at least one global variable.Compare and contrast separate function files with anonymous functions. In your opinion, when may it be best to use one over the other? Can you use them interchangeablyin all circumstances?

12. John is used to doing programming in Python and since the print() function in Python by default prints a newline after printing the string passed to the print() function. But in his current project, he is using PHP programming language and the echo function does not print a newline by default after the end of the string. So, he often misses giving a newline after printing a message. Help David by writing a function myecho() that takes a string as a parameter and also prints a newline after printing the string.
I need help in preparing a the pseudo code and a flow chart following the process below. 1. Start/Begin 2. Access the digital music library (collection) 3. Sort the songs collection by category (example: Rock, Pop, Country, Hip hop etc.) // for the sake of this problem we are only considering the Song category Pop 4. Sort the Pop songs (an array of pop songs) 5. Eliminate the duplicate songs out of the list (eliminate duplicate element in the array) 6. Sort the new Song list (an array of pop songs) 7. Eliminate songs whose duration is not a whole number (an array of pop songs whose duration is not whole number) 8. Sort the Song list alphabetically (an array of pop songs) 9. Name the list of songs as My_playlist 10. Eliminate the songs in the list to restrict the whole duration of the playlist is not less than 60 mins and greater than 70 mins (sum the duration of the elements of the array not exceeding 60 mins and greater than 70). 11.

Look at the differences between max1 and max22. What is the difference?3. Do the two functions do the same amount of computation?4. If so, do you think that the two functions will run in the same amount of time? #include <stdio.h>#include <time.h>#include <stdlib.h> // For the assignment, be sure to run unmodified code, but you are free to // play around with the code to try out different parameters or different// implementations. // arrs is a 16384 element array of 256 integer arrays (a 2D array)// each function is run 50 times (numiters) in order to increase the runtime// into the range of seconds (which is the time printed) int max1(int** arrs, int narrs, int arrlen) { int max = 0; for (int i=0; i<narrs; i++) { for (int j=0; j<arrlen; j++) { if (arrs[i][j] > max) max = arrs[i][j]; } } return max;} int max2(int** arrs, int narrs, int arrlen) { int max = 0; for (int j=0; j<arrlen; j++) { for (int i=0; i<narrs; i++) {…
You should submit a script file and a plain text output file (.txt) that contains the test output. Multiple file uploads are permitted. Don’t forget to include descriptive comments in your Python code. Your submission will be assessed using the following Aspects. Does the submission include the is_divisible function from Section 6.4 of the textbook? Does the submission implement an is_power function that takes two arguments? Does the is_power function call is_divisible? Does the is_power function call itself recursively? Does the is_power function include code for the base case of the two arguments being equal? Does the is_power function include code for the base case of the second argument being "1"? Does the submission include correct output for the five test cases?
Your task is to implement a variation of the classic word game Hangman, which involves playersguessing the letters in a word chosen at random with a finite number of guesses. While there arealternate versions such as category Hangman and Wheel of Fortune, which involve playersguessing idioms, places, names and so on, we will be sticking with the traditional version. Requirements:You will implement a function called main that allows users to play an interactive hangman gameagainst the computer. The computer should pick a word, and players should then try to guess lettersin the word until they win or run out of guesses.Here is the overarching behaviour we expect:1. The program should load a list of available words from the text file provided. Note thatthe file you have been given contains words in lowercase.2. The computer should then select a word at random from the list at random.3. The user is given a certain number of guesses at the beginning.4. The game is interactive; the user…
What is a stub? Group of answer choices A stub is an inline function with a single line that simply sends a "Hello" message to others, indicating that it has been activated. A stub is a function that has an empty body. It will be developed later. A stub is an inline function with a single line that simply increases the pass in value by one. A stub is a function with a single line that simply prints the name of the function, indicating that it has been activated. A stub is a short function that will generate an error message.
1. Consider the following list definitions. lista = [1, 2, 3, 4, 0] listb = [3, 0, 2, 4, 1] listc = [3, 2, 4, 1, 5] What is the value of the following expressions? If you think the expression raises an error, just type 'error' (without quotes) in the input box. a. lista[0] b. lista[lista[1]] c. listb[listb[2]] d. lista[listb[2]] e. listc[lista[listb[3]]] f. lista[listc[lista[listb[0]]]] g. lista[listc[lista[listb[3]]]] h.
write a python code named get_total_cases() takes the a 2D-list (similar to database) and an integer x from this set {0, 1, 2} as input parameters. Here, 0 represents Case_Reported_Date, 1 represents Age_Group and 2 represents Client_Gender (these are the fields on the header row, the integer value represents the index of each of these fields on that row). This function computes the total number of reported cases for each instance of x in the text file, and it stores this information in a dictionary in this form {an_instance_of_x : total_case}. Finally, it returns the dictionary and the total number of all reported cases saved in this dictionary. (Suppose we want to know the total number of cases reported on each date, so use x = 0.) >>> result, total_cases = get_total_cases(database, 0) >>> display_dict(result) 2021-05-19: 8 2021-05-20: 2 2021-05-21: 1 2021-05-22: 1 >>> print(total_cases)
Analyze the ChatGPT output by answering the following questions. Data types Which data types would be accepted by the function count_crossings_and_nestings for the argument arcs? Would a set work? What does the function return? What data type is it? Run the example suggested by ChatGPT. Is the function count_crossings_and_nestings working as expected? Try computing nestings and crossings with the smallest examples {}, {(0,1)}, {(0,1),(2,3)}, {(0,3),(1,2)} and {(0,2),(1,3}. Does the output work?

Use the Bash shell for the completion of this project.Develop a shell scripting application that allows the user to perform some advanced mathematicaloperations. Task 2: Find the terms of any linear sequence given by the rule Term = a*n + b, where a and b are integers specified by the user and n is a positive integer and print them in order (for example if the user inputs a=3, b=-4, the first few terms that should be printed are -1, 2, 5, 8, 11…). The user also will specify how many terms the program should print. In addition, the program should print the sum of terms found and a count of how many odd terms were found.
