OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.

- code Connect6State.java according to the following instructions Class Connect6State java.lang.Object Connect6State public class Connect6State extends java.lang.Object Connect6State - A representation of a Connect6 (http://en.wikipedia.org/wiki/Connect6) game state. We assume a square grid board size specified to be a positive integer less than or equal to 26. Size 19 is common. The first and second players place pieces on the board that are black and white, respectively. Each piece is placed in an unoccupied grid position. On the first turn, the first player places one piece. Afterwards, players alternate placing two pieces per turn. Play continues until either one player completes a consecutive line of 6 or more of their pieces or no play is possible. The player with 6 or more pieces in a horizontal, vertical, or diagonal line is the winner. If no legal play is possible, the game is a draw. Field Summary Fields Modifier and Type Field Description static int…Artificial Intelligence - Local Search Starting from a randomly generated state of the 15-puzzle game (https://en.wikipedia.org/wiki/15_puzzle), steepest-ascent hill-climbing (the vanilla version of hill-climbing search) gets stuck 76% of the time, i.e., solving only 24% of problem instances. But it works very quickly, i.e., it takes just 6 steps on average when it succeeds and 5 steps when it gets stuck. In contrast, if sideways moves are allowed, this raises the percentage of problem instances solved by hill-climbing from 24% to 81%, with the success at a cost: the algorithm averages roughly 7 steps for each successful instance and 32 steps for each failure. Now suppose that we are implementing random-restart hill climbing (i.e., if a search fails, it keeps to try, and try, until it gets a success) by the following two versions: one uses vanilla steepest-ascent hill climbing, and the other one uses hill climbing with sideways moves. Can you please tell which version of…Python Language Q2: Ginormous Campus The campus is pretty big. There are n buildings scattered around it, numbered from 0 to n-1. These buildings are so far away from each other that the only way to get from one to another is to take a campus bus. There are m campus bus routes. The i-th one (0 <= i < m) takes you from building u_i to building v_i (but not the other way around). These buses run very frequently. Professor Zingaro is deciding where to hold his CS lectures. He believes a building x is accessible from a building y if you can get from y to x taking at most two buses. For his students’ convenience, he wants to hold his lectures in the most accessible building. Help him out by telling him how many buildings the most accessible building is accessible from. In addition, list all buildings that are the most accessible. Input The first line of the input contains two space-separated integers n and m, denoting the number of buildings and bus routes, respectively. m lines…
- MastermindIn this assignment, you will program the well-known game Mastermind. In Mastermind, player 1creates a pattern consisting of a pre-approved number of colored pins. Then player 2 has to guessthis pattern in as few turns as possible. Each turn, player 2 can guess what the pattern mightbe. Player 1 will then tell player 2 how many correct colors were guessed, and how many of thosecorrectly guessed colors were guessed in the right place. Player 2 can then use this information toimprove their guess for the next turn. When player 2 guesses the correct pattern, the game ends.Write a program that acts as player 1 of the Mastermind game. This program will generate a(random) pattern, and will play according to the game’s rules, with a human acting as player 2.The program should stop when the user guesses the pattern.Additionally, the program has to conform with the following specifications:1. Because of practical reasons, the pattern will consist of capital letters instead of colors.2.…Complete the code below to have a scaling rectangle java. public void start(Stage primaryStage) { // create a rectangle with width 50, height 80 and color blue ……………………………………………………………………………………………………………………………………………………………………………………………………………… // create the transition ……………………………………………………………………………………………………………………………………………………………………………………………………………… // set the duration of the transition as 5 seconds ……………………………………………………………………………………………………………………………………………………………………………………………………………… // make the rectangle as the node for the transition ……………………………………………………………………………………………………………………………………………………………………………………………………………… // transition to double the size of x ……………………………………………………………………………………………………………………………………………………………………………………………………………… // transition to double the size of y ……………………………………………………………………………………………………………………………………………………………………………………………………………… // set the cycle count as 2…Correct answer will be upvoted else Multiple Downvoted. Don't submit random answer. Computer science. every cell of the network contains a non-negative integer. Each turn, a player should play out every one of the accompanying activities all together.

Pick any of the most limited ways between the two cells and either increment, lessening or leave the upsides of cells on this way unaltered. Note that: a most limited way is one that goes through the most un-number of cells; all cells on this way barring the beginning cell, yet the completing cell might be altered; the subsequent worth of every cell should be a non-negative integer; the cells are changed freely and not really by a similar worth.

- Q3: Interplanetary Spaceflight Milan Tusk is the richest person in the universe. After devoting decades of his life to further our space exploration technologies, he’s finally ready to retire. Being a space enthusiast, the first thing he wants to do is visit n planets p1, p2, …, pn, in this order. He’s currently on planet p0. Milan knows that the distance between planets pi and pi + 1 (for 0 ≤ i < n) is d[i]light years. His spaceship uses 1 tonne of fossil fuels per light year. He starts with a full tank and can fill up his tank at any of the n planets (but he must not run out in between two planets). There’s a huge cost to set up the spaceship for refuelling. Due to financial constraints (he’s not THAT rich), he can fill up his tank at most ktimes. In order to save money and make his spaceship lighter, Milan is looking for the smallest possible fuel tank that enables him to complete his space travel and reach planet pn. What is the smallest tank capacity that enables him to do so?…QUADRATIC PRIMES This question is adopted from Project Euler Question 27. (https://projecteuler.net/problem=27) The quadratic formula n^2 + n + 41 will produce 40 primes for consecutive integer values 0 <= n <= 39. However, when n = 40, this formula will not generate a prime number. Another interesting quadratic formula n^2 – 79n + 1601 produces 80 prime numbers for consecutive values 0 <= n <= 79. The Question: find a and b such that when -999 <= a <= 999 and -1000 <= b <= 1000, the quadratic form ?^2 + ? × ? + ? produces the maximum number of primes for consecutive values of n, starting with n = 0. Requirement: MUST BE WRITTEN IN C++ - Print the 40 primes generated by formula n 2 + n + 41 - Print the 80 primes generated by formula n 2 – 79n + 1601 - Write a function that takes in an integer and returns whether the given number is prime or not. - Output the value of a, b and how many consecutive values of n (count the starting zero!) can be generated. - Submit…Class Connect6State Cloneable Connect6State - A representation of a Connect6 game state.
