Correct answer will upvoted else downvoted. framework of size n×m, with the end goal that every cell of it contains either 0 or 1, is considered lovely if the total in each adjoining submatrix of size 2×2 is actually 2, i. e. each "square" of size 2×2 contains precisely two 1's and precisely two 0's. You are given a network of size n×m. At first every cell of this network is unfilled. How about we indicate the cell on the crossing point of the x-th line and the y-th segment as (x,y). You need to handle the inquiries of three sorts: x y −1 — clear the cell (x,y), in case there was a number in it; x y 0 — compose the number 0 in the cell (x,y), overwriting the number that was there already (assuming any); x y 1 — compose the number 1 in the cell (x,y), overwriting the number that was there beforehand (assuming any). After each question, print the number of ways of filling the unfilled cells of the grid so the subsequent network is delightful. Since the appropriate…Give a description of a TM M, that recognizes language D = {w over {0, 1}*| w contains twice as many 0's as l's}. For example: 010 E D, 000011 E D, and 0110 € D. In this case, you are free to use in your description traditional or any variation of TM we have covered in class. • In addressing be sure to pay special attention to final (halting) configurations, when required. you are expected to provide pseudocode for the corresponding machines. Remember that in your pseudocode, you need to be clear of what are your reading and writing on the tape (and which tape if you use more than 1), the direction in which the tape heads will move, and when the Turing Machine should halt and accept and/or halt and reject. Having said that, the point is not for you to describe state-by-state what the Turing Machine would look like. Instead, the goal of the description is for you to offer a high level overview that considers what to read/write in which order, in which directions the tape would move and…
- Let L = { w | w cannot be written as st#ts with s, t {a, b}* }. Show that L is not regular.Please write Lisp code for the following problem.

The function should return whichever node in mylist is nearest to v (in the sense of the minimum weight path from v). In the event of a tie, it should return the nearest node which appears earliest in mylist. CORDELIA WEBB UNIVERSITY OF LEEDS, 2023/24 B2 We say that a weighted graph has the Unique Weight Prop- erty (UWP) if no two edges have the same weight. Recall from Workshop 9-10 that if G is connected and has the UWP then it will automatically have a unique spanning tree. Write a func- tion UWP (G) which tests whether or not G has the UWP and returns True or False accordingly. Hint: extract a list of edge-weights and use the count func- tion to see how many times each appears.

- Implement the following two functions that allow breaking a string into non-empty tokens using a given delimiter in c language . For example, ● For a string “abc-EFG-hi”, and a delimiter ‘-’ : the list of tokens is [“abc”, “EFG”, “hi”] ● For a string “abc-EFG---hi-”, and a delimiter ‘-’ : the list of tokens is [“abc”, “EFG”, “hi”] ● For a string “abc”, and a delimiter ‘ ’ : the list of tokens is [“abc”] ● For a string “++abc++”, and a delimiter ‘+’ : the list of tokens is [“abc”] That is, we break the string using the given delimiter, and the tokens are only the non-empty substrings.Implement the following two functions that allow breaking a string into non-empty tokens using a given delimiter in c language .

Using Lisp, write a program that solves the Missionaries and Cannibals problem that uses a DFS( depth first search). It should use (mac start end). Start is the current state (which can be (3 3 l) and End is the goal state (which can be (0 0 r). This should output the sequences of moves needed to reach the end state from the start state. This should print nil if there is no solution. For example, the call should be something like this! Call: (mac '(3 3 l) '(0 0 r)) Output: ((3 3 l) (2 2 r) (3 2 l) (3 0 r) (3 1 l) (1 1 r) (2 2 l) (0 2 r) (0 3 l) (0 1 r) (1 1 l) (0 0 r))
- Write a function that multiplies two polynomials in HASKELL multPoly :: (Num a, Eq a) => Poly a -> Poly a -> Poly a For example: > multPoly (P [-1,0,1]) (P [0,1])P [0,-1,0,1]> multPoly (P [-1,0,1]) (P [2])P [-2,0,2]> multPoly (P [1,1]) (P [-1,1])P [-1,0,1]> multPoly (P [18,0,3]) (P [])P [] Before writing multPoly, you may find it helpful to write a function that increases the degree of a polynomial by multiplying it by x. E.g., mapping x^2−1 to ?^3−x. Seeing how this function, scale, and addPoly are written should give you a sense of how to construct multPoly. As with addPoly, multPoly is easier to write as a combination of simpler functions. Your implementation of multPoly should have this property: multPoly p q $$ x == (p $$ x) * (q $$ x)IN HASKELL PROGRAMMING LANGUAGE PLEASE In case you do not know it: the game is played on a 3x3 grid that is initially empty. Two players are playing, by alternatingly making moves. A move by a player places their token (an X for player 1, an O for player 2) into a cell that was empty. We are using algebraic notations for indexing the positions in the board, with A,B,C indexing the columns and 1,2,3 the rows. Specifically, these coordinates would be used in the implementation for moves made by a human player. If the X X O Figure 1: Sample board position same token appears 3 times in any of the three columns, three rows or two main diagonals the game is over and that player wins. If the grid is filled without that happening the game is a draw. For the depicted board, we have Xs in positions C3 and A2, and an O in position B1. It would be O’s turn to make a move; a legal move would be C2, but it is not a good move, because X can force a win by responding A1. O cannot force a win, but…In C language, implement the following two functions that allow breaking a string into non-empty tokens using a given delimiter. For example, For a string "abc-EFG-hi", and a delimiter '-': the list of tokens is ["abc", "EFG", "hi"] For a string "abc-EFG---hi-", and a delimiter '-': the list of tokens is ["abc", "EFG", "hi"] For a string "abc", and a delimiter ' ': the list of tokens is ["abc"] For a string "++abc++", and a delimiter '+': the list of tokens is ["abc"] That is, we break the string using the given delimiter, and the tokens are only the non-empty substrings. 1. The function count_tokens gets a string str, and a char delim, and returns the number of tokens in the string separated by delim. int count_tokens(const char* str, char delim); For example count_tokens("abc-EFG--", '-') needs to return 2. count_tokens("++a+b+c", '+') needs to return 3. count_tokens("***", '*') needs to return 0. 2.
