- Please give me the output code in python to the following scenario: Implement function links() that takes as input the name of an HTML file (as a string) and returns the number of hyperlinks in that file. To do this you will assume that each hyperlink appears in an anchor tag. You also need to know that every anchor tag ends with the substring</a>IN JAVA Create a function that takes a string and returns the number of alphanumeric characters that occur more than once. Examples duplicateCount ("abcde") → 0 duplicateCount ("aabbcde") → 2 duplicateCount ("Indivisibilities") → 2 duplicateCount ("Aa") → 0 // Case sensitiveWrite a python program that scans in a large number of tweets from a file, and prints the top 5 hashtags. Approach Parse each word in the file Find a way to isolate the hashtags from the rest of the tweet Compute the frequency of each unique hashtag. Find the top 5 hashtags. Caveats 1. Because this is public dataset, there are many tweets that use special characters that may cause issues during reading in your file. To avoid this, explicitly specify the encoding mode in open when reading in the file. with open('twitter_data.txt', 'r', encoding='utf8') as f: 2. When parsing hashtags be sure to change everything to lowercase. There are cases in the file where two hashtags are the same but differ in case. 3. There is no standard way of sorting a dictionary based on the values. Python gives you access to a sorted function where you can pass in a collection and also specify a comparator which outlines how you want to sort the values. This can be done with a one line lambda function.

For example: codes = { ‘A’ : ‘%’, ‘a’ : ‘9’, ‘B’ : ‘@’, ‘b’ : ‘#’, etc . . .} Using this example, the letter A would be assigned the symbol %, the letter a would be assigned the number 9, the letter B would be assigned the symbol @, and so forth. The program should open a specified text file (text.txt), read its contents, then use the dictionary to write an encrypted version of the file’s contents to a second file. Each character in the second file should contain the code for the corresponding character in the first file. Write a second program that opens an encrypted file and displays its decrypted contents on the screen. Below is the required dictionary. ➔➔➔➔➔➔➔➔ # Encryption and decryption are inverse of one another CODE =…
- In Java: The CSV (or comma-separated values) format is commonly used for tabular data. Each table row is a line, with columns separated by commas. Items may be enclosed in quotation marks, and they must be if they contain commas or quotation marks. Quotation marks inside quoted fields are doubled. Here is a line with four fields:1729, San Francisco, "Hello, World", "He asked: ""Quo vadis?""" Implement a class CSVReader that reads a CSV file, and provide methodsint numberOfRows()int numberOfFields(int row)String field(int row, int column)IN JAVA SCRIPT Programming Create a function that takes a string as an argument and returns true if each letter in the string is surrounded by a plus sign. Return false otherwise. Examples plusSign("+f+d+c+#+f+") → true plusSign("+d+=3=+s+") → true plusSign("f++d+g+8+") false plusSign("+s+7+fg+r+8+") → falseScenario: You have been tasked with building a URL file validator for a web crawler. A web crawler is an application that fetches a web page, extracts the URLs present in that page, and then recursively fetches new pages using the extracted URLs. The end goal of a web crawler is to collect text data, images, or other resources present in order to validate resource URLs or hyperlinks on a page. URL validators can be useful to validate if the extracted URL is a valid resource to fetch. In this scenario, you will build a URL validator that checks for supported protocols and file types.
- Create a subroutine that disassembles a simple noun-verb-object phrase into its constituent parts. As an illustration, the sentence "Mary walked the dog" may be deconstructed into the following:Noun: MaryVerb: walkedObject: the dog This function should work with both String objects and StringBuilder objects.Write a python program that creates a dictionary whose values are lists of anagrams of words read from a file. using: def norm(s): def AnagramDicionary(f): def printWordList(L): def main():An “inverted file” is a critical data structure for implementing applications like the index of a book, or a web search engine. Given a document D (which can be viewed as an unordered, numbered list of words), an inverted file is an ordered list of words L such that for each word W in L, we store the indices of the places in D where W appears. Write a C# program (from scratch please, written by yourself (ask instructor if you are stuck), not borrowed from any other sources) that reads in a list of words separated by spaces from a text file, then uses an efficient O(N) algorithm to create the inverted file index (hint: consider the topic of this chapter, consider using a Dictionary/hashtable to help you), and writes this index out to another file or prints it to the screen. Each line of the output file should start with the next word (the words should be listed in alphabetical order, and this sorting does not have to be part of the O(N) runtime complexity, e.g. you can use regular…
