- Programming Language: C++ Create a structure Student and ask the user how many students. Create an array which will save the number of students in the input. Ask for the data of the first and last student and display them.Exercise: empty_dictionary Description In this exercise, your function will receive no parameters. It will create an empty dictionary and return it. Function Name empty_dictionary Parameters None Return Value An empty dictionary. Examples empty_dictionary() > 0)Overview This program will have you use a loop to prompt a user for three foods and their country of origin and then store them in a dictionary called food_dict). Then, it will prompt the user for a dish that they like and then will tell them the country of origin. Expected Output Example 1 What is good to eat? Tacos What country is that from?

- PYTHON PROGRAMMING Given:lunch_order = {'food': 'pizza', 'price':9.99 } 1) Update the value of 'price' from 9.99 to 6.99 in the dictionary lunch_order.2) Access the values in the dictionary lunch_order to print the following.Make sure to precisely match the output format below. Example OutputToday's lunch special: Pizza $6.99.Median Function – In statistics, the median of a set of values is the value that lies in the middle when the values are arranged in sorted order. If the set has an even number of values, the median is the average of the two middle values. Your program should start with two arrays of integers containing the following values: Even numbered array: 17 32 45 68 99 101 67 89 22 27 Odd numbered array: 17 32 45 68 99 101 67 89 22 Using a sort function of your choice, first sort the arrays. NOTE: you may use the Standard Template Library sort function or your own sort function. Then, write a function that determines the median of a sorted array. The function should take an array of numbers and an integer indicating the size of the array and return the median of the values in the array. The same function should be called twice – once for the even array and once for the odd array. Your program should also have a printArray function that can be used to print the sorted array. (It…Python program named "YourMuseumID_Exhibits.py" focusing on museum exhibit data: You have a list of dictionaries representing exhibits in a museum. Each dictionary contains the exhibit name, the number of artifacts on display, and the historical era it covers. Perform the following tasks: (a) Calculate and display the total number of artifacts on display for all exhibits in the museum. (b) Identify and display the exhibit with the highest number of artifacts on display. (c) Implement a function that takes a user-input exhibit name and searches for it in the list. If found, display the number of artifacts on display and the historical era it covers; if not found, print a message indicating that the exhibit is not in the museum. (d) Implement a sorting algorithm of your choice to sort the exhibits based on the number of artifacts on display in descending order and display the sorted list. Make sure to incorporate functions for each task and display the results in the main function with…
- ▾ Part 2: Course Registration The time has come to register for courses at Stony Brook University. Complete the function register, which takes three arguments: a dictionary that maps a course's name to its number of credits (course_credits); a list of courses a student wants to take (courses); and a maximum number of credits the student is willing to take (max_credits). The function iterates over the courses list and attempts to register the student for each course, in sequence (use a for-loop, not a while-loop). "Registering" for a course means to add the number of credits of a course to a running total. If registering for a course would bring the total number of credits over max_credits, skip that course and continue on to the next one in the courses list. The function returns the total number of credits the students successfully registered for. Example #1: register ({'MAT 131': 4, 'PHY 131': 3, 'AST 200': 1, 'WRT 102': 3, 'PHY 133': 1}, ['MAT 131', 'WRT 102'], 12)) Return value: 7…PYTHON CODING This function takes a list of points and then returns a new list of points, which starts with the first point that was given in the list, and then followed by points closest to the start point.

- Dictionary Swap Write a function called dictionary_swap that takes a dictionary as a parameter. It does not modify the original dictionary, but it creates and returns a new one. Keys from the original dictionary become values in the new one, and values become keys. For example, given the inputs below, your program should return the corresponding values. Input to the Function Returns {'one':1, 'two': 2, 'three':3} {1:'one', 2:'two', 3:'three'} {-1:-10, -2:-20, -3:-30} {-10:-1, -20:-2, -30:-3} {} {}Word FrequencyWrite a python program that reads the contents of a text file. The program should create a dictio-nary inwhich the keys are the individual words found in the file and the values are the number of timeseach word appears. For example, if the word “the” appears 128 times, the dictionary wouldcontain an element with 'the' as the key and 128 as the value. The program should eitherdisplay the frequency of each word or create a second file containing a list of each word and itsfrequency.PHP Write a reduce function Write a function reduce($arr, $func) that takes an array and a function as a parameter. The reduce function should apply the parameter function to each element of the array in succession to produce a single result. Note: the current result should always be the first parameter to the function and the next element of the array should always be the second parameter. You may not use the PHP function array_reduce in your solution. For example, the result of the following should be 10. function myMax($current, $new) { return $current < $new ? $new : $current; } $arr = array(10, 5, 3, 5, 1, 2, 5, 7, 4); print("Max: " . reduce($arr, 'myMax') .
