- Counting hashtags Write Python code to count the frequency of hashtags in a twitter feed. Your code assumes a twitter feed variable tweets exists, which is a list of strings containing tweets. Each element of this list is a single tweet, stored as a string. For example, tweets may look like: tweets = ["Happy #IlliniFriday!", "It is a pretty campus, isn't it, #illini?", "Diving into the last weekend of winter break like... #ILLINI #JoinTheFight", "Are you wearing your Orange and Blue today, #Illini Nation?"] Your code should produce a sorted list of tuples stored in hashtag_counts, where each tuple looks like (hashtag, count), hashtag is a string and count is an integer. The list should be sorted by count in descending order, and if there are hashtags with identical counts, these should be sorted alphabetically, in ascending order, by hashtag. From the above example, our unsorted hashtag_counts might look like: [('#illini', 2), ('#jointhefight', 1),…Lab Task 04: Include the methods in the file KMP_Implementation.txt in a complete Java program that prompts for and reads a text string and then a text pattern to search for in the text. It then displays the result of the search. Sample program runs: Enter the text: ABABСАВАВАВСАВАВСАВАВСАВАВКККАВАВСАВАВ Enter the pattern to search for: ABABCABAB Pattern found at these text starting indexes: 0 Enter the text: A KFUPM STUDENT Enter the pattern to search for: KFE Pattern not in text. 7 12 17 29The getBytes() method of String returns a byte array representation of the string Select one: True False
- Write a program that reads a sentence and store it in an array of characters. The program also reads a word and store in it a string variable. The program then conceals the word in the sentence with the character @'. Sample input / output: Enter a sentence: The town in which we live is a green town and big Enter a word: town Result: The @aa@ in which we live is a green @@@@ _and bigDesign a program that allows two players to play a game of tic-tac-toe. Use a two dimensional String array with three rows and three columns as the game board. Each element of the array should be initialized with a asterisk (*). The program should run a loop that does the following: Display the contents of the board array. Allows player 1 to select a location on the board for an X. The program should ask the user to enter the row and column number. Allows player 2 to select a location on the board for an O. The program should ask the user to enter the row and column number. Determines whether a player has won or if a tie has occurred. If a player has won, the program should declare that player the winner and end. If a tie has occurred, the program should say so and end. Player 1 wins when there are three X's in a row on the game board. Player 2 wins when there are three O's in a row on the game board. The winning X's or O's can appear in a row, in a column, or diagonally…Computer Science JAVA #7 - program that reads the file named randomPeople.txt sort all the names alphabetically by last name write all the unique names to a file named namesList.txt , there should be no repeats
- e. Why does the String Writer class use a String Buffer to perform its work?Write a program named Search.java that uses a function called search_string to check whether a string exists in the array or not. 1- The array of strings is iterated using a for loop and the value at every index is compared with the value to be searched in the array. 2- A boolean variable is set if any array value matches with the string. 3- At the end of the loop, this boolean variable is checked to determine if the array contains the string. Hint: You may need to import java.util.Arrays then use Arrays.toString, String equals(). The ouput should look like what is pictured below. Please provide an editable code that is easy to copy and paste.The function last_words in python takes one parameter, fname, the name of a text file, and returns a list containing the last word from each line of the file. For example, if the file contents are: apples are red bananas are yellow limes are green then the list ["red", "yellow", "green"] should be returned. NOTE: You may assume the file will contain no blank lines. BIG HINT: If line is a string representing a line of text (inside a for loop!), then L = line.split() creates a list of the words in the line. For example: Test Result L = last_words("wordlist1.txt") print(L) ['happy', 'sad', 'angsty', 'euphoric', 'maudlin']
- Manhattan skyline def manhattan_skyline(towers):This classic problem in computational geometry (essentially, geometry that can be done using only integer arithmetic; yes, that is an actual thing) is best illustrated by pictures and animations such as those on the page "The Skyline problem", so you can first check that it out to get an idea of what is going on. Given a list of rectangular towers as tuples (s, e, h) where s and e are the start and end x-coordinates (satisfying e>s) and h is the height of that tower, compute and return the total visible area of the towers, being careful not to double count two or more towers that are partially overlapping. All towers share the same flat ground baseline at the height. The classic solution illustrates the important sweep line technique that starts by creating a list of precisely those x-coordinate values where something relevant to the problem takes place. In this problem, the relevant x-coordinates are those where some tower either…Read the string variables visitedListName, place1, place2, and place3 from input, assuming that the list's name contains multiple words and each place visited is a single word. The first input line contains the list's name and the second input line contains the places visited. Ex: If the input is: Countries I've visited Qatar Zambia Malta then the output is: Countries I've visited: Qatar Zambia Malta #include <iostream> #include <string> using namespace std; int main() { string visitedListName; string place1; string place2; string place3; /* Your code goes here */ cout << visitedListName << ":" << endl; cout << place1 << endl; cout << place2 << endl; cout << place3 << endl; return 0; }True/False 7. The split method breaks a string into a list of substrings, and j oin does the opposite.
