- def height(words, word): The length of a word is easy enough to define by tallying up its characters. Taking the road less traveled, we define the height of the given word with a recursive rule for the height of the given word to follow from the heights of two words whose concatenation it is. First, any character string that is not one of the actual words automatically has zero height. Second, an actual word that cannot be broken into a concatenation of two nonempty actual words has the height of one. Otherwise, the height of an actual word equals one plus the larger of the heights of the two actual words whose combined concatenation it can be expressed as. To make these heights unambiguous for words that can be split into two non-empty subwords in multiple ways, this splitting is done the best way that produces the tallest final height. Since the list of words is known to be sorted, you can use binary search (available as the function bisect_left in the bisect module) to quickly…Try to create a dictionary that has a listing of people and includes one interesting fact about each of them. Display each person and their interesting fact on the screen. From there, alter a fact about one of the people on the list. Also, add an extra person and corresponding fact to the list. Display the newly created list of people and facts. Try running the program multiple times and take note of whether the order changes.given dictionaries, d1 and d2, create a new dictionary with the following property. For each entry(a,b) in d1, if a is not a key of d2 then add (a,b) to the new dictionary. For each entry (a,b) in d2, if a is not a key of d1 then add (a,b) to the new dictionary. For example, if d1 is {2:3, 8:19, 6:4, 5:12} and d2 is {2:5, 4:3, 3:9}, then the new dictionary should be {8:19, 6,4, 5:12, 4:3, 3:9}. using puthon
- what are the values returned for foo(4,2) and foo(5,3) respectively?This question is in java The Sorts.java file is the sorting program we looked at . You can use either method listed in the example when coding. You want to add to the grades.java and calculations.java files so you put the list in numerical order. Write methods to find the median and the range. Have a toString method that prints the ordered list, the number of items in the list, the mean, median and range. Ex List: 20 , 30 , 40 , 75 , 93Number of elements: 5Mean: 51.60Median: 40Range: 73 Grades.java is the main file import java.util.Scanner;public class grades { public static void main(String[] args) { int n; calculation c = new calculation(); int array[] = new int[20]; System.out.print("Enter number of grades that are to be entered: "); Scanner scan = new Scanner(System.in); n = scan.nextInt(); System.out.println("Enter the grades: "); for(int i=0; i<n; i++) { array[i] = scan.nextInt(); if(array[i] < 0) {…Complete the Swap() method in main.c to exchange the values of the num field of two Number struct objects, num1 and num2.
- Retrieving a value using its associated key can be accomplished using anindexer, which works just like an indexer for an array. A key is passed in asthe index value, and the value associated with the key is returned, unless thekey doesn’t exist, in which a null is returned.Write short code segment demonstrates how this technique works:PROGRAM IN C++ Our BoardArray will store 5 entries maximum. Improve the following existing methods: bool add(entry* e) Improve the add method where you will return true if the entry has been successfully added (i.e. the entry is placed in the top 10), otherwise return false (i.e. if the entry did not make it to the top 10). bool remove(const char* person) Improve the remove method where you return true if an entry is successfully deleted (i.e. we have found an entry that matches the person), otherwise return false. Add the following additional methods: bool ban_country(const char* nation) Removes all the entries bearing the country equal to the given nation. Return true if at least one entry has been removed, otherwise return false. int country_wins(const char* nation) Returns the number of entries in the scoreboard who represents the given nation. int exemplary(int score) Returns how many entries in the scoreboard are greater than or equal to the given score. double…Using Clojure Write a procedure, called count-to-1, that takes a positive integer n, and returns a list of the integers counting down from n to 1. For example, given input 3, it will return (list 3 2 1). Hint: Use the procedures reverse and count-to-n that you wrote in the previous problems. (Shown in attached image)
- Please explain the questions related to the code below: //1. Why is 20 printed 3 times and why does it start with 1, but end with 2? //2. What is the base case for this recursive method and why? //3. How would you implement this using a loop? //4. What is each if statement checking? //5. Would a solution to this using loops require more or less code and would it be more or less effecient? //6. Why is recursion a good choice to solve this problem? //7. How can recursion become infinite? //8. When is recursion appropriate? /* Load the code below into a cloud compiler and run each method one at a time by removing the comments for the method. Walk through the code as a group and explore how the code works. Submit the answers to the numbered questions for credit. */ public class DemoRecur { //Simple statement designed to show control flow in recursion public static void printDemo(int x, int max) {…Write a C program for this problem: The partially initialized array "table" can be viewed as a primitive spreadsheet, in which the last column and bottom row have been left blank. Write the code to fill in this row and column with the totals of each column, each row, and the GRAND TOTAL. PS. Don't forget to add comments for every step you make.Note that you can only use recursion to solve Q1 and you cannot use any loop. You are free to add helper methods, but you are not allowed to change the method header.Question 1: Crazy seriesIn this session, you need to implement the crazy series method. In the crazy series, you will be given a starting number. Then, you need to times 2 for each number until the number is greater than 100. After the number is greater than 100, you need to divide 3 until we reach the number is less than 5. Note that the input number must be greater than 0, and you are not allowed to use loop here.For example,crazySeries(10) should return ArrayList [10.0, 20.0, 40.0, 80.0, 160.0, 53.333333333333336, 17.77777777777778, 5.9259259259259265, 1.9753086419753088]crazySeries(5) should return ArrayList [5.0, 10.0, 20.0, 40.0, 80.0, 160.0, 53.333333333333336, 17.77777777777778, 5.9259259259259265, 1.9753086419753088]crazySeries(1) should return ArrayList [1.0, 2.0, 4.0, 8.0, 16.0, 32.0, 64.0, 128.0,…
