- Octave assignment 1-Introduction to Octave Introduction This assignment is meant to be a gentle introduction to Octave, the free version of Matlab. It assumes that you have no prior coding experience. Objectives Download Octave and run it or use https://octave-online.net/ Learn the basics of the Octave GUI. • Learn how to create a short executable file called an m-file (.m extension) and run it. • Learn what a data type is. • Learn how to declare variables of different data types. • Learn how to create matrices. • Learn how to use several of Octave’s functions for creating objects with random numbers. Instructions 1.) Create a file call it with the form exercise_1_first name_last name. Include the underscores in your file name. At the top of the file add the comment "“My first Octave assignment. I'm so excited, I just can't hide it." 2.) Create the following variables a = 2.3; b = -87.3; A = [1,2; 4,5]; Create a matrix 2 × 2 B using the rand() function. Create two random complex…Virus DNA files As a future doctor, Jojo works in a laboratory that analyzes viral DNA. Due to the pandemic During the virus outbreak, Jojo received many requests to analyze whether there was any viral DNA in the patient. This number of requests made Jojo's job even more difficult. Therefore, Jojo ask Lili who is a programmer for help to make a program that can read the file containing the patient's DNA data and viral DNA and then match them. If on the patient's DNA found the exact same string pattern, then write to the index screen the found DNA. Data contained in the file testdata.in Input Format The first line of input is the number of test cases TThe second row and so on as many as T rows are the S1 string of patient DNA and the S2 string of viral DNA separated by spaces Output Format The array index found the same string pattern. Constraints 1 ≤ T ≤ 1003 ≤ |S2| ≤ |S1| ≤ 100|S| is the length of the string.S will only consist of lowercase letters [a-z] Sample Input (testdata.in)…- used multiple Scanner objects • - use substring() to get the first char • use charAt() to get the last char
- Assume that you are designing a simple text editor (like Notepad) that supports inserting text, copy, paste and editing for any size file (including book-length files). Between the String objects and StringBuffer objects, which one is more appropriate and why? O String, because StringBuffer is read-only String, because it will execute more efficiently String, because only simple operations are needed StringBuffer, because it allows for changing the characters stored in the object StringBuffer, because it has copy and paste methodsJAVA PPROGRAM Write a program that prompts the user to enter a file name, then opens the file in text mode and reads names. The file contains one name on each line. The program then compares each name with the name that is at the end of the file in a symmetrical position. For example if the file contains 10 names, the name #1 is compared with name #10, name #2 is compared with name #9, and so on. If you find matches you should print the name and the line numbers where the match was found. While entering the file name, the program should allow the user to type quit to exit the program. If the file with a given name does not exist, then display a message and allow the user to re-enter the file name. The file may contain up to 100 names. You can use an array or ArrayList object of your choosing, however you can only have one array or ArrayList. Input validation: a) If the file does not exist, then you should display a message "File 'somefile.txt' is not found." and allow the…Java Program: Make sure that names are able to be written to a binary file via aserializable interface
- Please DO NOT respond to this question by copy/pasting the code provided elsewhere on the site, none of those work. Thanks. Virtual Memory Lab This lab project addresses the implementation of page-replacement algorithms in a demand-paging system. Each process in a demand-paging system has a page table that contains a list of entries. For each logical page of the process, there is an entry in the table that indicates if the page is in memory. If the page is in memory, the memory frame number that page is resident in is indicated. Also, for each page, the time at which the page has arrived in memory, the time at which it has been last referenced, and the number of times the page has been referenced since the page arrived in memory are maintained. The page table data structure is a simple array of page-table entries (PTEs). Each PTE contains five fields as defined below: struct PTE { int is_valid; int frame_number; int arrival_timestamp; int…Create a program to compress and decompress a file.

- USING PYTHON: Create a function that takes a filename("string") of a PGM image file as input and loads in the image in the file, and returns it as an image matrix. Rules: Cannot make any input calls in the main body, use basic python (nothing like .shape or .width) I have attached an example of what the function should do, as well as what the PGM image file looks like.Select the right choice of the multiple questions Queue .as a (FIFO) data container. ........... Select one: a. save b. work c. givenAn application loads 100 libraries at start-up. Loading each library requires exactly one disk access. The seek time of the disk to a random location is given as 10 ms. Rotational speed of disk is 6000 rpm. If all 100 libraries are loaded from random locations on the disk, how long does it take to load all libraries? (The time to transfer data from the disk block once the head has been positioned at the start of the block may be neglected.)
