Topological Sort

Topological sort is a sorting technique that sets up a hierarchy in a process. In this technique, when a directed network has nodes connected by arrows, the root node is placed before the successor node.

C++ Programming, Arrays Lights The park is illuminated by n (1 < n < 100) lights. Each of them shines all night or not. Of course, which lights were on the first night and which were not. Every other night the condition of the lamps shall be determined by the following rules: the lamp will not illuminate if both of its neighbors were lit last night; the lamp shall illuminate if one of its neighbors was illuminated last night and the other was not; if neither of the first two rules applies to the lamp, it will illuminate when the night is even and will not illuminate when the night is odd. Create a program to determine which lights are on and which will not be lit when k (1 < k < 100) nights have elapsed, and to find which night the most lights were lit and which the least. If there are several identical nights with the most or least lights lit, the night with the lower number must be indicated.

O'caml Sliding tiles (35%) The mechanics described in this exercise can be used to implement a game sliding tiles. For basic description of the game see https://en.wikipedia. org/wiki/Sliding_puzzle. 1. Create a type slidingTile, consisting of a char matrix and two integers x and y. The integers x and y are the coordinates of an empty tile. 2. Create a function val slide : slidingTile -> int -> int -> slidingTile = that given a slidingTile and two integers, that represent a location in the matrix, it slides the tile from the specified location to the empty tile, then returns the altered slidingTile. If provided location is not adjacent to the empty tile, or out of bounds, then return the slidingTile unaltered. 3. Create a function val print_tile : slidingTile -> unit = that prints a slidingTile on screen with the corresponding characters from the matrix. However, print an empty space where the empty tile is instead.

Python problem Problem statementDevelop a program that receives a matrix and determines whether it corresponds to a magic square. A magic square is one that the sum of its elements in each of the rows is equal to the sum of the elements in each of the columns and also equal to the sum of the elements of each of the diagonals. The condition that the numbers from 1 to n ** 2 are used must also be met, where n is the size of the magic square, which is a matrix of nxn. https://upload.wikimedia.org/wikipedia/commons/thumb/e/e4/Magicsquareexample.svg/1200px-Magicsquareexample.svg.png EntryThe first line corresponds to the number n. After this, n lines, each line contains a list of integers separated by a space. DepartureIf the square is magic, it must print the value that has the sum of the numbers by columns, rows and main diagonals. If it is not a magic square, the word "Error" must be printed without quotation marks. Examples Input Example 1 416 3 2 135 10 11 89 6 7 124 15 14 1Output…
