Problem 2 (Match Lines – smaller version) program called t7_p2.py read_file(filename) n n n x n and add the following functions to this program.reads the text file named board.csv (available in the tutorial folder) that contains some strings on each line. Your function must check if the data represents a matrix, i.e., if there are number of lines on the file, there must be number of comma separated strings on each line of that file. If the data represents a matrix, your function must store those data in a 2-D list of size and return it. Otherwise, it must return an empty list.check_line(list, row, col, dir) takes four input parameters; list is a 2D list of size n x n, row and col are integers, and dir is a string. You function must do the following operation.o Check if row and col values are between 0 and n-1 inclusive. If not return False.o Check if dir is either “up”/”down”/”left”/”right”. If not return False.o Check if list contains same 3 symbols in the given direction (dir)up/down/left/right. If yes return True. Otherwise return False.• main( ) function must read the csv file to create a 2-D list. Ask users for valid inputs for row, col and dir, and prints if the user found a line of 3 matching symbols on the given location and in the given direction. Your function must use your other functions for reading the csv file and matching lines.the last picture is the board file

Subject: Computer organization and Assembly LanguageQuestion. Add $t0, $s1, $s2Convert the above code into binary code as per MIPS format and register numbers. Specify the type of instruction (R, I or J)Question. Sll $t2, $s0, 4 Specify the operation performed by the instruction and write the machine code (binary code) for it in MIPS, clearly specifying all fields of the instruction. Show the contents of all registers before the execution of the program and after the execution. You can assume that S0 contains 1234 before start of program. Note: It is a complete question. Graph, link or other material etc. are not used and required. I will very Thankful to you if you solve this question.

Hi there! I need somebody to help me in the following the negotiated-congestion routing (NCR) allows for temporary routing violations and maintains history costs for every routing segment. Thesehistory costs can decrease the significance of net ordering. Given that NCR can beadapted to track-based detailed routing, give several reasons why net orderingremains important in area routing.If you studied EDA in masters please answer this otherwise I’ll give unhelpful!

Dont copy from other answersif user enters 1, 25, 34 then tick should be like thisturnright 1turnleft 25 turnright 34locker is openedWrite Java class ComboLock that works like the combination lock in a gym locker. The lock is constructed with a combination, three numbers between 0 and 39. The reset method resets the dial so that it points to 0. The turnLeft and turnRight methods turn by a given number of ticks to the left or right. The open method attempts to open the lock. The lock opens if the user first turned it right to the first number in the combination, then left to the second, and then right to the third. The class and its methods’ signatures are as follows: public class ComboLock { . . . public ComboLock(int secret1, int secret2, int secret3) { . . . } public void reset() { . . . } public void turnLeft(int ticks) { . . . } public void turnRight(int ticks) { . . . } public boolean open() { . . . } } Also, provide a tester class, ComboLockTester, that tests the above class using various combinations entered by a user inside a loop. User will exit from the loop by entering three 0s as the combination.

Hi, I’ve uploaded my web server in Hereku. It’s working on my localhost. Unfortunately, it’s showing application error in Heroku. Thanks!Here is my sever:var express = require(“express”);var app = express();var bodyParser = require(‘body-parser’);const Handlebars = require(“handlebars”);const { body, validationResult } = require(‘express-validator’);var HTTP_PORT = process.env.PORT || 3000;app.use(express.static(__dirname “/views”));app.get(“/”, function(req,res){ res.sendFile(__dirname “/views/index.html”); });app.get(“/room”, function(req,res){ res.sendfile(__dirname “/views/roompage.html”);});app.post(‘/action_page’, [ body(‘username’).isEmail(), body(‘password’).isLength({ min: 5 })], (req, res) => { const errors = validationResult(req); if (!errors.isEmpty()) { return res.status(400).json({ errors: errors.array() }); } User.create({ username: req.body.username, password: req.body.password }).then(user => res.json(user));});app.post(‘/form-reg’, [ body(‘username’).isEmail(), body(‘password’).isLength({ min: 5 }) ], (req, res) => { const errors = validationResult(req); if (!errors.isEmpty()) { return res.status(400).json({ errors: errors.array() }); } }); app.listen(HTTP_PORT);

Devise a main algorithm to input nmySequence( n )na1=5, a2=3, a3=2an= an-3 – an-2 – an-1 when n>3 as a number greater than 2, and call a sub-algorithm that returns an array with elements that represent the following series: hint: this series will look like: 5, 3, 2, 0, 1, 1, -2, 2, 1, -5, … where 5, 3, and 2 are initial values and the remaining values are calculated as 0=5-3-2, 1=3-2-0, 1=2-0-1, -2=0-1-1, etc.then, the main algorithm outputs how many values of this series (with n elements) are odd. You may want to devise another sub-algorithm here too.As an example, if n is 3, the algorithm outputs 2 because in 5, 3, and 2, there are two odd numbers.As another example, if n is 7, the algorithm outputs 4 because in 5, 3, 2, 0, 1, 1, and -2, there are four negative numbers.
