- In this assignment, you will write a program that readsa list of people from a file, create a HashSet of the people, and print the people in the HashSet.The input filename ispassed in as a command line argument.•The program must implement a main class, and a Person class.•A template for the Person class is provided.A Person has a name and an address, both Strings.•If the input file name is not provided, your program should an error message and exit, e.g., Usage: java FuAssignment10/FuMain inputfile•If the specified input file does not exist or cannot be opened, your program should an error message and exit, e.g.,File abc.txt does not existor cannot be opened!•The input file lists one person per line. Each line contains aname and an address, separated by a comma, “,”.For example, the following are in a sample file students.txt:James Bond, 111 Main StTayer Smoke, 2334 Murry LnDavid Jones, 302 Toast AveAbby Wasch, 84 Sunny PlJames Bond, 111 Main St•Yourprogram should read each line,…Write a program that reads words from a file (filename given as a string parameter) and prints the occurance of each word(case insensitive). And print the words in alphabetical order. For example, if the file contains text Love is free free is love then the function should print free:2 is:2 love:2 def count_word(filename): # YOUR CODE HERE raise NotImplementedError()Write a program that reads movie data from a CSV (comma separated values) file and output the data in a formatted table. The program first reads the name of the CSV file from the user. The program then reads the CSV file and outputs the contents according to the following requirements: Each row contains the title, rating, and all showtimes of a unique movie. A space is placed before and after each vertical separator ('|') in each row. Column 1 displays the movie titles and is left justified with a minimum of 44 characters. If the movie title has more than 44 characters, output the first 44 characters only. Column 2 displays the movie ratings and is right justified with a minimum of 5 characters. Column 3 displays all the showtimes of the same movie, separated by a space. Each row of the CSV file contains the showtime, title, and rating of a movie. Assume data of the same movie are grouped in consecutive rows. Hints: Use the find() function to find the index of a comma in each row of…
- Make use of a random number generator to generate a list of 500 three-digit numbers. Create a sequential list FILE of the 500 numbers. Artificially implement storage blocks on the sequential list with every block containing a maximum of 10 numbers only. Open an index INDX over the sequential list FILE which records the highest key in each storage block and the address of the storage block. Implement Indexed Sequential search to look for keys K in FILE. Compare the number of comparisons made by the search with that of the sequential search for the same set of keys.Extend the implementation to include an index over the index INDX.Write a program that inputs a list of integers from the user, and removes the duplicate list elements, plus outputs their min and max values.Write a program that obtains the executiontime of external sorts for integers of size 6,000,000, 12,000,000, 18,000,000,24,000,000, 30,000,000, and 36,000,000. Your program should print a tablelike this:
- Write a program that first reads in the name of an input file and then reads the input file using the file.readlines() method. The input file contains an unsorted list of number of seasons followed by the corresponding TV show. Your program should put the contents of the input file into a dictionary where the number of seasons are the keys, and a list of TV shows are the values (since multiple shows could have the same number of seasons). Sort the dictionary by key (least to greatest) and output the results to a file named output_keys.txt. Separate multiple TV shows associated with the same key with a semicolon (;), ordering by appearance in the input file. Next, sort the dictionary by values (alphabetical order), and output the results to a file named output_titles.txt. Ex: If the input is: file1.txt and the contents of file1.txt are: 20 Gunsmoke 30 The Simpsons 10 Will & Grace 14 Dallas 20 Law & Order 12 Murder, She Wrote the file output_keys.txt should contain: 10: Will…Write a python program that reads the contents of a text file. The program should create a dictionary in which the keys are the individual words found in the file and the values are the number of times each word appears. For example, if the word "the" appears 128 times, the dictionary would contain an element with 'the' as the key and 128 as the value. The program should either display the frequency of each word or create a second file containing a list of each word and it's frequency. This program has really been giving me trouble. Any help is great appreciated. Thanks so much!need code for this in python or java thanks
- Please write a program using python that will create a dictionary and keep count of how many words of certain length are seen in a known text file. For example, in text file "example.txt" there are 5 words; chocolate, mild, separate, question, and. This would produce: {8:2, 9:1, 4:1, 3:1}Without using the built in java hash table Write a Java program to get input from the keyboard to enter an integer.Write a hash function to hash the integer.Store the integer in a DataItem object.Create a hash table to store the DataItem in the hash table at the hashed location.Write a function to search a hash function for an integer value and display it from the DataItemobject at the hashed locationIn JAVA, use a HashMap to count and store the frequency counts for all the words from a large text document. Then, display the contents of this HashMap with given words and their frequency in the document. Next, please create a set view of the Map and store the contents in an array. Sort this array based on key value and display it. Finally, sort the array in decreasing order by frequency and display it.
