in javascript create a function that does the following and named as such, please dont copy the already answered question of this in the incorrect manner thank you!! grouper( xs, n ) This function takes a list of elements xs and an integer n. The function groups every n elements in xs as a list and returns a list of those groups. Each group in the resulting list will therefore be of length n, with the possible exception of the final group. The final group must be non-empty. Examples grouper( [1,2,3,4,5], 2 ) => [[1,2], [3,4], [5]] grouper( ['a','b','c','d','e'], 4 ) => [['a','b','c','d'],['e']] grouper( [], 3 ) => []
Computer ScienceA restaurant requires WAIT ADT to help waiter to wait tables. Theapplication is required to provide functions to add a food item to the WAITlist, remove an item from the Wait list, size of the list i.e., the food itemsordered, and know if item is already in the list. The WAIT ADT access timeshould be O [1]. Provide implementation details with your choice of datastructure and the operations with justification of the constant access time.Implement search food in the added Wait list in C.
A list is sorted in ascending order if it is empty or each item except the last one is less than or equal to its successor. Define a predicate isSorted that expects a list as an argument and returns True if the list is sorted, or returns False otherwise. (Hint: For a list of length 2 or greater, loop through the list and compare pairs of items, from left to right, and return False if the first item in a pair is greater.) Below is an example of a main function and the associated output: def main(): lyst = [] print(isSorted(lyst)) lyst = [1] print(isSorted(lyst)) lyst = list(range(10)) print(isSorted(lyst)) lyst[9] = 3 print(isSorted(lyst)) True True True False

An “inverted file” is a critical data structure for implementing applications like the index of a book, or a web search engine. Given a document D (which can be viewed as an unordered, numbered list of words), an inverted file is an ordered list of words L such that for each word W in L, we store the indices of the places in D where W appears. Write a C# program (from scratch please, written by yourself (ask instructor if you are stuck), not borrowed from any other sources) that reads in a list of words separated by spaces from a text file, then uses an efficient O(N) algorithm to create the inverted file index (hint: consider the topic of this chapter, consider using a Dictionary/hashtable to help you), and writes this index out to another file or prints it to the screen. Each line of the output file should start with the next word (the words should be listed in alphabetical order, and this sorting does not have to be part of the O(N) runtime complexity, e.g. you can use regular…
Use the main template provided in the breakout room activity onto your IDE. Add the implementation for the print_categories(), is_valid_index() and update_category() functions Test your implementations by running the assert tests in the test file. Requirements You will need to implement the following functions. def print_categories(main_list): """ Given a list of lists, for each list stored in main_list, output its contents as follows: f"{index of category}. {item[0]} - {item[1]}%". note that indexing must start at 1 for the first item, not 0, which is first item's actual index in main_list. If `main_list` is empty, the function prints "There are no categories." Returns the number of categories. """ pass def is_valid_index(idx, in_list): """ Checks whether the provided index `idx` is a valid positive index that can retrieve an element from `in_list`. Returns False if `idx` is negative or exceeds the size of `in_list` - 1. """ pass def update_category(info_str, idx, main_list): """…
in C++... kth Element Extend the class linkedListType by adding the following operations:a. Write a function that returns the info of the kth element of the linked list. If no such element exists, terminate the program.b. Write a function that deletes the kth element of the linked list. If no such element exists, terminate the program. Provide the deﬁnitions of these functions in the class linkedListType. PLEASE DON'T reject this question, this is the whole question that I have... so please do it however u can, Thank you!

code in scala def unfold[A, S](z: S)(f: S => Option[(A, S)]): LazyList[A] = f(z) match { case Some((h, s)) => h #:: unfold(s)(f) case None => LazyList() } [Note: #:: is the Cons constructor of LazyLists] A triple (x, y, z) of positive integers is pythagorean if x2 + y2 = z2. Using the functions studied in class, define a function pyth which returns the list of all pythagorean triples whose components are at most a given limit. For example, function call pyth(10) should return [(3, 4, 5), (4, 3, 5), (6, 8, 10), (8, 6, 10)]. [Hint: One way to do this is to construct a list of all triples (use unfold to create a list of integers, and then a for-comprehension to create a list of all triples), and then select the pythagorean ones.
There’s a somewhat imperfect analogy between a linked list and a railroad train, where individual cars represent links. Imagine how you would carry out various linked list operations, such as those implemented by the member functions insertFirst(), removeFirst(), and remove(int key) from the LinkList class in this hour. Also implement an insertAfter() function. You’ll need some sidings and switches. You can use a model train set if you have one. Otherwise, try drawing tracks on a piece of paper and using business cards for train cars.
Create class IntegerSet for which each object can hold integers in the range 0 through 100. Represent the set internally as a vector of bool values. Element a[i] is true if integer i is in the set. Element a[j] is false if integer j is not in the set. The default constructorinitializes a set to the so-called “empty set,” i.e., a set for which all elements contain false . Provide an intersectionOfSets member function which creates a third set which is the set-theoretic intersection of two existing sets (i.e., an element of the result is set to false if that element is false in either or both of the existing sets, and an element of the result is set to true if that element is true in each of the existing sets).
in PYTHON, please Given a base Plant class and a derived Flower class, write a program to create a list called my_garden. Store objects that belong to the Plant class or the Flower class in the list. Create a function called print_list(), that uses the print_info() instance methods defined in the respective classes and prints each element in my_garden. The program should read plants or flowers from input (ending with -1), add each Plant or Flower to the my_garden list, and output each element in my_garden using the print_info() function. Note: A list can contain different data type and also different objects. Ex. If the input is: plant Spirea 10 flower Hydrangea 30 false lilac flower Rose 6 false white plant Mint 4 -1 the output is: Plant Information: Plant name: Spirea Cost: 10 Plant Information: Plant name: Hydrangea Cost: 30 Annual: false Color of flowers: lilac Plant Information: Plant name: Rose Cost: 6 Annual: false Color of flowers: white Plant…
