In this coding challenge, you will be retrieving email usernames from a string. You will write a function named get_usernames () that takes in a string as it's input parameter, and returns a list of email usernames in the string. The input strings will contain 0 or more emails in the format username@domainname, and the '@' symbol will only appear in the context of an email. The order of usernames should match the order in the input text. For example: EXAMPLE 1 text: "If you need help on an assignment, email help@ucsd.edu or support@gmail.com" return: ['help', 'support'] EXAMPLE 2 text: "Good morning! I hope you're having a great time with CSE 8A!" return: [] EXAMPLE 3 text: "I've been having a lot of trouble reaching you, can you please email me at cse@ucsd.edu? return: ['cse', 'cse'] Here is the problem description: Function Name: get_usernames Parameter: text - A string corresponding to a piece of text containing 0 or more emails. Return: A list of the email usernames in the input text. Description: Given a piece of text, extract all email usernames and return them in a list.

The acclaimed _NumPy_ library, that `Simpy` is inspired by, allows you to use the subscription operator not just to select individual items, but also to filter with a mask. It adds a second usage to the operator, just like you have had two uses of many of the operators above, such as adding two `Simpy`s or a `Simpy` and a `float`. The big idea of the second usage of subscription notation is that if instead of giving an `int` inside the subscription brackets you give a `list[bool]`, the expression will return a new `Simpy` object containing only the _masked_, or filtered, `values`. For example: ~~~python a = Simpy([1.0, 2.0, 3.0, 4.0, 2.0, 1.0]) mask = a > 2.0 print(mask) # Output: [False, False, True, True, False, False] b = a[mask] print(b) # Output: Simpy([3.0, 4.0]) ~~~ The above example did not need to establish a separate variable named `mask`, it only did so to make it obvious what the `mask` values were. More conventionally, the above example would be written in a…

I'm working on an assignment and i'm trying to create a to-do list in AndroidStudio. I've created the listview, edit text, switch and button, but I've hit a snag with the following: Create a new Java object to hold each todo item, it should contain a string with the text of the todo, and a boolean for if it is urgent or not. Create a List to hold all your items, and for the adapter to use for displaying them. When you click “Add”, you should create a new todo item and add it to the list, clear out the text in the EditText, and call “notifyDatasetChanged()” on your adapter so it refreshes. Implement a BaseAdapter to power the ListView. In AndroidStudio, type ctrl + O (the letter ‘O’, not number zero). From the list of inherited functions, implement these ones: int getCount() - This returns the number of rows that will be in your listView. In your case, it should be the number of strings in the array list object ( return list.size() ). Object getItem(int position) – This…
Your Task: Remove any word that does not start with a capital letter. For instance, for the input text of "Hello, 2022 world!", we should get "Hello, 2022 !". Notes: As in the previous question, you can safely assume that the set of characters that will be used will be only among the following: alphabetical characters [A-Za-z] (upper and lower case English letters), numerics [0-9] (digits), the space character [ ], and the following 6 punctuations: [.,!?;:]. You can define a word as follows: starts with a letter [A-Za-z], then proceeds with alphanumeric characters [A-Za-z0-9] until hits a non alphanumeric character (so a space character or a punctuation). However, if for simplicity, you take each word to be allowed to start with numeric characters too, that is fine as well (your outputs will be considered as valid). So for instance, the words like 2way, 4door, etc or even numbers like 2022 are also valid words. STARTER CODE: .data buffer_for_input_string: .space 100…
Question 4 Write a function that will redact every third word in a sentence. Make use of the hashtag (#) symbol to redact the characters that make up the word, i.e. if the word is five characters long then a string of five hashtags should replace that word. However, this should not redact any of the following punctuation marks: apostrophes (') quotations (") full stops (.) commas (,) exclamations (!) question marks (?) colons (:) semicolons (;) Arguments: sentence (string) →→ sentence that needs to be redacted. Return: redacted sentence (string)→→ every third word should be redacted. Expected outputs sentence = "My dear Explorer, do you understand the nature of the given question?" redact_words(sentence) == 'My dear ########, do you ########## the nature ## the given ########?' sentence = "Explorer, this is why you shouldn't come to a test unprepared." redact_words(sentence)=="Explorer, this ## why you #######'# come to # test unprepared."
For example, suppose the word “robot” is found in lines 7, 18, 94, and 138. The dictionary would contain an element in which the key was the string “robot”, and the value was a list containing the numbers 7, 18, 94, and 138. Once the dictionary is built, you should prompt the user for a word. If the word is found in the dictionary, then print out all the lines on which they are found in ascending order. The code for the print out is provided in the stub code. A stub code is provided for you.

In JAVA, use a HashMap to count and store the frequency counts for all the words from a large text document. Using file util, please. Then, display the contents of this HashMap with words and frequency count. 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 as well. Please label your explanation in the code Thank you

Use the Iterator Pattern: Create a class called Exercise, and then, in its main method, create an ArrayList called stringArrayList. Add the following five strings to stringArrayList: “one”, “two”, ”three”, ”four”, ”five”. Then, use a for loop and the index of stringArrayList to print all these five strings out to the console. 2. For stringArrayList above, can you use an iterator to traverse the five strings inside, without using the index? 3. If change stringArrayList into a TreeSet, how do you traverse the five strings use an iterator? Implement an Iterator: 4. Create a class called StringArray that is able to store a number of String objects. Create an instance variable, String[] values, (internal data storage) of StringArray to store all the strings. 5. Create a constructor for StringArray, which is able to build an object of StringArray using the parameter. public StringArray(String[] values) 6. Make the class StringArray implements Iterable So that it…
