Problem 2. Rob has successfully installed Spark in Ubuntu. He also runs the WordCount example successfully. He now can start understanding each line in the WordCount.py file. He opens the pyspark shell. Suppose that the Spark context "sc" is already defined when he opens the shell. He wants to load the data "/home/rob/data/peterpan.txt". The command he uses is $ book = sc.textFile("/home/rob/data/peterpan.txt")

- Implement a simple version of the linux grep command in C++. grep - Looks through a file, line by line, trying to find a user-specified search term in the line. If a line has the word within it, the line is printed out, otherwise it is not. Use the system calls open(), getline(), close(). Requirements (examples run from. terminal) Your program grep is always passed a search term and zero or more files to grep through (thus, more than one is possible). It should go through each line and see if the search term is in it; if so, the line should be printed, and if not, the line should be skipped. [terminal]$ ./grep ! main.cpp main2.cppcout << "Hello, World!";cout << "Programming is great fun!"; The matching is case sensitive. Thus, if searching for world, lines with World will not match. Lines can be arbitrarily long (that is, you may see many many characters before you encounter a newline character, \n). grep should work as expected even with very long lines. For this,…Write a program to manage a set of graphical objects based on the commands in a specifiedfile. This is a graphical equivalent of the famous edlin tool for text manipulation.On the Vula page of the assignment, you will find VectorGraphics and Question2classes that will handle the file I/O for you. When you run Question2, specify the file namelike this: java Question2 myfile.in Each line of the file contains an instruction in one of the formats given below: a <id> <x> <y> rectangle <x_length> <y_length> a <id> <x> <y> hline <x_length> a <id> <x> <y> vline <y_length> a <id> <x> <y> ptline <y1> <y2> w d <id> m<id><x> <y> x Explanation:‘a’ adds an object of a particular type (rectangle/hline/vline/ptline) with the specifiedparameters.‘w’ renders/draws the objects and prints the composite image to the screen.‘d’ deletes an object based on its id.‘m’ moves an…Implement a simple version of the linux cat command in C++. Use the system calls open(), get() and close(). cat - reads a file as specified by the user and prints its contents. A typical usage is as follows: If from my terminal y run ./cat main.cpp the contents of main.cpp. will be printed. Your program cat can be invoked with one or more files on the command line; it should just print out each file in turn. Example: [terminal]$ ./cat main.cpp main2.cpp #include <iostream>using namespace std;int main(){cout << "Hello, World!"; return 0;}#include <iostream>using namespace std;int main(){cout << "Programming is great fun!";return 0;} As you can see content of main.cpp was printed first and the content of main2.cpp
- In this laboratory work, you are expected to write a c# console application to make some operations about the customers. Operations and required featurest that you need to cover in your program are following: • Add: This function adds a new person to json file. You need to get inputs from user and adds the new one into json file. • Display: This function displays all people in your json file. • Search: This function let you search with the user id. • Create Password: This function will create a random password for the user and user may choose the length of the password. Password may include numbers and characters. • Exceptions: You need to handle exceptions as well. You should at least handle 3 of exceptional cases. For the case that file can not be found, It is mandatory to catch the exception. Sample json string: "FirstName": "Kaan", "LastName": "OZAYDIN", "EmployeeId": 101, "Email": "", "Password": "Address": ( "ZipCode": "06460", "State": "Ankara", "Country": "Turkey" "FirstName":…Using PyCharm, create a new Project lab12. Under lab12 create a new Directory exercise,then create a Python file called name.py in which to writea class named Name. This class holds the entire name of a person, that is, first, middle and last names and a suffix, and keeps count of how many of these names are being used (this is explained below). 1. The class has the following fields: count, first, middle, last and suffix.2. The class has a constructor that receives one string parameter named name whose default value is an empty string (that is, calling the constructor with no parameters sets the value of name to an empty string). The constructor initializes all fields based on the value of name, as explained next: – The value of count depends on the number of words in name. For example,given the name Robert John Downey Jr then count is 4.– If name has one word then it has a first name.– If name has two words then it has a first and last names in that order.– If name has three words…Write a program that asks the user for a number of seconds and prints out how many minutes and seconds that is. For instance, 200 seconds is 3 minutes and 20 seconds. [Hint: Use the // operator to get minutes and the % operator to get seconds.] Your answer should be a Colab shared file. You only need to turn in the LINK and change the sharing option so that I can access and run the code. Any solution that can not be accessed will be ignored.

- Write a function extractData in your shell script wparser.bash. This function will perform the core processing logic associated with each file. The main script will just iteratively call this function with different files as its argument. This function should accept a data file as its argument. This function should then produce an output of the following format that that contains only the temperature and wind information from the sensors along with a header. (see image; truncated for brevity). A clean format of data like this form can be used by various information processing systems. The script is basically only including the year, month, day and hour information, followed by the temperature reported by each temperature sensor, and wind speed from wind sensors at that time. If a temperature sensor’s reading is NOINF or MISSED SYNC STEP in the original data file for that particular time, the script must instead output the previous readout for that temperature sensor. For…Write a test client which takes a file path as an argument and reads each line one by one. The file can contain any number of DNA sequences (i.e., Strings.). After reading each DNA sequence, your code should print the DNA sequence first. Please follow the screenshot below for the output format. If the DNA sequence is valid DNA, report that and print out its complement as well as whether or not it is a Watson-Crick complemented palindrome. If the DNA sequence is not a valid DNA, only report that. Continue this process for each DNA sequence in the text file. Separate the outputs for each sequence by printing a line as shown in the screenshot. In your project directory, create a new directory named ‘in’. The in folder will contain the input text file, titled sequences.txt. To run the code, your program argument should be in/sequences.txt Method Summary. Return Type Method 1 boolean isValid(String DNA) 2 String…Suppose you have Java source files under the directorieschapter1, chapter2, . . . , chapter34.
