- Project Description: In this project you implement an ArrayStack ADT and use the stack for implementing the following methods: a) Reverse an array of Words: Accept an array of words as input parameter and return an array of words in reverse order. Use the method signature: public static String[] reverseWords (String[] wordList) Example Input: Bird Cat Dog Elephant Output: Elephant Dog Cat BirdEQrite a java program to read from a file called "treeList.txt". The file includes tree height, and tree age for unknown number of trees. The file use a comma separated file format, as the sample below. The program should write old trees only into an output file called "oldTrees.txt". A tree is considered old if its height is above 120 and its age is greater than 5 years. Finally print number of old trees at the end of the output file and format the output file to be similar to the given sample. treeList.txt oldTrees.txt 15.000,5 Tree Height Age 130.500,7 1. 130.500 7 140.000,6 2. 140.000 150.800,3 100.200,8 Number of old trees = 2.Project Description: In this project you implement an ArrayStack ADT and use the stack for implementing the following methods: a) Reverse an array of Words: Accept an array of words as input parameter and return an array of words in reverse order.

In the first version of the game, we will only be comparing horizontally for a win. A win is determine by all of the elements in a row either being an X or an O. You need to return a String with the winner or TIE if there is no winner. ticTacToe(["X", "O", "O"], ["X", "O", "O"], ["X", "X", "X"]) → "X"ticTacToe(["X", "O", "X"], ["X", "X", "O"], ["O", "O", "O"]) → "O"ticTacToe(["X", "O", "X"], ["X", "X", "O"], ["O", "X", "O"]) → "TIE" public String ticTacToe(String[] top, String[] middle, String[] bottom) { }def q5(sentence): Assumes sentence is a string. Returns a list of all the words in sentence, where a word is a token separated by white space, (you can use sentence.split()), and then for each word, make it lowercase and remove any character that is not alpha-numeric (a-z or 8-9). For example, I q5("The Plague" (French: "La Peste"), 1947, by Albert CamUs.') should return ['the', 'plague', 'french', 'la', 'peste', '1947', 'by', 'albert', 'camus'] q5('Red@Dragon....ca is great!') should return ['reddragonca', 'is', 'great'] pass# define stemmer functionstemmer = SnowballStemmer('english') # tokenise datatokeniser = TreebankWordTokenizer()tokens = tokeniser.tokenize(data) # define lemmatiserlemmatizer = WordNetLemmatizer() # bag of wordsdef bag_of_words_count(words, word_dict={}): """ this function takes in a list of words and returns a dictionary with each word as a key, and the value represents the number of times that word appeared""" for word in words: if word in word_dict.keys(): word_dict[word] += 1 else: word_dict[word] = 1 return word_dict # remove stopwordstokens_less_stopwords = [word for word in tokens if word not in stopwords.words('english')] # create bag of wordsbag_of_words = bag_of_words_count(tokens_less_stopwords) Use the stemmer and lemmatizer functions (defined in the cells above) from the relevant library to find the stem and lemma of the nth word in the token list.
