Implement a function cousins(person, family) with the following specification. Input: A string containing a person's name, person, and a family tree database family as specified above. Output: A list containing the names of all cousins of person that are stored in the database, or an empty list if no such information exists in the database (including if the person themselves is not in the database). For example, cousins should behave as follows, after reading in the provided hobbit-family.txt file: >> hobbits = read_family('hobbit-family.txt') >> sorted(cousins('Frodo Baggins', hobbits)) ['Daisy Baggins', 'Merimac Brandybuck', 'Milo Burrows', 'Saradoc Brandybuck', 'Seredic Brandybuck']

Implement the following functions in the same application in C#: 1. Given a number (integer) N (greater than 1). Implement a Fibonacci sequence of length N. (Function name ComputeFibonacciSequence )ComputeFibonacciSequence receives N.2. Given a list L with n numbers (integers), implement a function that returns whether that list is even prone or not (i.e.: the number of even numbers in the list must be higher than that of the odd numbers.) (Function name ComputeEvenProne) - Return 1 if the list is even prone, return 0 if it is not.ComputeEvenProne receives L.
Write in C++ Now, what if Sam wants to insert Eevee after Pikachu but he doesn't know where Pikachu is located in his list. Let's help him search for a Pokemon by its name and insert another Pokemon directly after it. Write a function secondPlace() that takes six parameters and inserts a new Pokemon into a list right after another specified pokemon. Once you find the specified Pokemon, use the insertAfter() function from the previous sub-question to add the new Pokemon. The function should return the new number of strings in the array. Note The same Pokemon may appear in the list multiple times (Sam has a bad memory). Assume that Sam wants every instance of the Pokemon he is searching for to be followed by the Pokemon he is attempting to insert. If the array is already full or if the number of strings that are going to be added to the array plus the current number of strings exceeds the total size of the array, the array should remain unchanged. Assume all inputs are lowercase…
Please implement the follwoing problem in C++: Implement a symbol balance checker function for the Pascal programming language. Pascal allows for the following pairs: {}, (), [], begin end . All programs will begin with the word "begin" and end with the word "end". Your function should receive an ifstream object which is already open and will return true, all of the symbols match, or false, they do not. You do not have to worry about comments in the program but you do have to avoid other parts of the program's code such as assignment statements (x=y) and other expressions.
QUESTION: NOTE: This assignment is needed to be done in OOP(c++/java), the assignment is a part of course named data structures and algorithm. A singly linked circular list is a linked list where the last node in the list points to the first node in the list. A circular list does not contain NULL pointers. A good example of an application where circular linked list should be used is a items in the shopping cart In online shopping cart, the system must maintain a list of items and must calculate total bill by adding amount of all the items in the cart, Implement the above scenario using Circular Link List. Do Following: First create a class Item having id, name, price and quantity provide appropriate methods and then Create Cart/List class which holds an items object to represent total items in cart and next pointer Implement the method to add items in the array, remove an item and display all items. Now in the main do the following Insert Items in list Display all items. Traverse…
for c++ A set is a collection of distinct elements of the same type. Design the class unorderedSetType. Design the class unorderedSetType, derived from the class unorderedArrayListType, to manipulate sets. Note that you need to redefine only the functions insertAt, insertEnd, and replaceAt. If the item to be inserted is already in the list, the functions insertAt and insertEnd output an appropriate message. Similarly, if the item to be replaced is already in the list, the function replaceAt outputs an appropriate message. Write a program to test your class.
this code should be in python: write a function that receives a list as its only parameter. Inside the function remove all the duplicate items from the list and returns a new list. For Example: If we call the function with [“dad”, “aunt”, “mom”, “sister”, “mom”] as its input, the returned value should be [“dad”, “aunt”, “mom”, “sister”]. The order of the items inside the returned list does not matter.
Python Question QUESTION 1 Recursively count the occurrences of a substring. Implement a function that counts the number of times a target string occurs in the main string. In particular, provide the implementation for count(s, target), where 's' is the main string and 'target' is the substring you wish to count. Note that 'target' is not just a single character, but a substring of any length greater than zero (length guaranteed to be positive). Some of the sample cases include, but are not limited to, the following. Input: s= 'aaabbb', target = 'aa' Output: 2 Input: s= 'bbaaa', target = 'c' Output: 0 Input: s= 'abcbc', target='bcb' Output: 1 Input: s = 'aab', target='bbbb' Output: 0 Here are the constraints: • You mustn't use any of the string methods provided by Python. (Indexing is okay) • You must use recursion. • Write a paragraph detailing the base and recursive cases. Your answer should also include the *why* and *how*.
IN MAGICFS LANGUAGE The Fibonacci sequence begins like this: 0,1,1,2,3,5,8,13,21,... A number in the sequence is the sum of the previous two numbers in the sequence, with first two being 0 and 1. Implement a function named 'fibonacci' that expects a working value of an integer index, and returns the Fibonacci number at that position in the sequence. The index is zero-based. For instance, if given a value of 4, the function should return 3 because the sequence is 0, 1, 1, 2, 3, ... Use subroutines if necessary. Your answer will be evaluated for partial credit. Comments are encouraged.
Please answer it in Python Write a function last_consonant that takes as an argument a word and returns two return values: the index of its last consonant as well as the last consonant (as for lists, we will consider that the index of the first letter is zero). We will not deal with the problematic case where the word does not contain a consonant. Example: last_consonant('arrivee') returns 4, 'v' Write a function double_consonant that takes as an argument a word and has two return values: a Boolean worth True if the word contains a double consonant (twice the same consonant in a row), and in this case the second return value is the consonant that is doubled; If there is no doubled consonant, the function must return False and None. If the word contains several double consonants (for example, 'successor'), true will be returned and the first double consonant appearing in the word. Examples: double_consonant('arrive') is true, 'r'. double_consonant ('candy') is false, None…
2. Write the definition of a bool function named BooleanMode () whose header is bool BooleanMode (bool data[), int n) Given that n represents the size of data, the function returns the truth value that appears the most in data. If there is an equal number of both truth values in data, the function returns the truth value that appeared first. For instance, if data = [true, true,false, false,false, true,falsel, then the function will return false. Impl
Write a function MedianWithoutHL(ScoreList) that takes an unsorted list of n numbers as a parameter, discards the highest and the lowest numbers and return the median. You can assume the number of items in the list is between 0.0 and 9.9. To find the median from a list of items, you have tosort the list and find out the value of the item in the middle.Note: If the list has an odd number of items, the median is the value of the middle item. If the list has an even number of items, the median is the average of the two middle items.Sample Run #1:scoreList1 = [9.0, 9.0, 7.5, 8.0, 9.5, 6.5, 5.0, 7.0, 7.5, 8.5]print("The Original ScoreList: ", scoreList1)print(MedianWithoutHL(scoreList1))Output of Sample Run #1:The Original ScoreList: [9.0, 9.0, 7.5, 8.0, 9.5, 6.5, 5.0, 7.0, 7.5, 8.5]The List after sorting: [5.0, 6.5, 7.0, 7.5, 7.5, 8.0, 8.5, 9.0, 9.0, 9.5]Without the High & Low: [6.5, 7.0, 7.5, 7.5, 8.0, 8.5, 9.0, 9.0]7.75
