- 8.26 LAB: Word frequencies (dictionaries) Implement the build_dictionary() function to build a word frequency dictionary from a list of words. Ex: If the words list is: ["hey", "hi", "Mark", "hi", "mark"] the dictionary returned from calling build_dictionary(words) is: {'hey': 1, 'hi': 2, 'Mark': 1, 'mark': 1} Ex: If the words list is: ["zyBooks", "now", "zyBooks", "later", "zyBooks", "forever"] the dictionary returned from calling build_dictionary(words) is: {'zyBooks': 3, 'now': 1, 'later': 1, 'forever': 1} The main code builds the word list from an input string, calls build_dictionary() to build the dictionary, and displays the dictionary sorted by key value. Ex: If the input is: hey hi Mark hi mark the output is: Mark: 1 hey: 1 hi: 2 mark: 1 Use Python, please.6.28 In Python, Write a program that replaces words in a sentence. The input begins with word replacement pairs (original and replacement). The next line of input is the sentence where any word on the original list is replaced. Ex: If the input is: automobile car manufacturer maker children kids The automobile manufacturer recommends car seats for children if the automobile doesn't already have one. the output is: The car maker recommends car seats for kids if the car doesn't already have one. You can assume the original words are unique.6.28 In Python, Write a program that replaces words in a sentence. The input begins with word replacement pairs (original and replacement).

- 8.13 LAB: Library book sorting Two sorted lists have been created, one implemented using a linked list (LinkedListLibrary linkedListLibrary) and the other implemented using the built-in Vector class (VectorLibrary vectorLibrary). Each list contains 100 books (title, ISBN number, author), sorted in ascending order by ISBN number. Complete main() by inserting a new book into each list using the respective LinkedListLibrary and VectorLibrary InsertSorted() methods and outputting the number of operations the computer must perform to insert the new book. Each InsertSorted() returns the number of operations the computer performs. Ex: If the input is: The Catcher in the Rye 9787543321724 J.D. Salinger the output is: Number of linked list operations: 1 Number of vector operations: 1 Which list do you think will require the most operations? Why?

The search() method should return the Node whose data value matches a given key, and None if the key is not found. The search() method should also set the position of each Node searched in the LinkedList, starting with 1. Ex: If the input is: 12 23 59 37 923 212the output is: 12 found in list at position 1.If the input is: 12 23 59 37 923 268the output is: 68 not found in list.13.14 LAB: Library book sorting Two sorted lists have been created, one implemented using a linked list (LinkedListLibrary linkedListLibrary) and the other implemented using the built-in ArrayList class (ArrayListLibrary arrayListLibrary).

Word pairs consist of a name and a phone number (both strings), separated by a comma. That list is followed by a name, and your program should output the phone number associated with that name. Output "None" if name is not found. Assume that the list will always contain less than 20 word pairs. Ex: If the input is: 3 Joe,123-5432 Linda,983-4123 Frank,867-5309 Frank the output is: 867-5309 Your program must define and call the following method. The return value of getPhoneNumber() is the phone number associated with the specific contact name.public static String getPhoneNumber(String[] nameArr, String[] phoneNumberArr, String contactName, int arraySize) Hint: Use two arrays: One for…Create the set objects A={L,M,N,P,Q} and B={L,R,S,P,T } .
