c++ or java HELP!! ASAP

5 (**). Hitori is a simple puzzle game played on an N N grid of positive integers. The idea is simply to cross out integers in the grid (as few as possible) so that: Any given number appears at most once in any given column or row; COSC 2436 S20 7 The remaining (unerased) numbers form a single connected group of squares, so that any unerased square is reachable from any other unerased square by a path of unerased squares that are adjacent horizontally or vertically; If a square is erased, its adjacent horizontal and vertical neighbors are not erased. So, given the initial grid (1), below, grid (2)is a solution. The other grids are not solutions for various reasons: (3)has two adjacent squares erased, (4)erases more squares than needed, and (5)breaks the unerased squares into unconnected groups. Of course, (1)itself is not a solution because it has duplicate numbers in several rows and columns. 1 2 5 3 1 2 5 3 1 2 5 3 1 2 5 3 1 2 5 3 4 2 2 2 4 2 2 2 4 2 2 2 4 2 2 2 4 2 2 2 3 6 3 5 3 6 3 5 3 6 3 5 3 6 3 5 3 6 3 5 2 4 5 1 2 4 5 1 2 4 5 1 2 4 5 1 2 4 5 1 (1) (2) (3) (4) (5) Write a program that, given such a grid, finds a solution satisfying the stated criteria. The input will come from the keyboard. Error check for positive board sizes from 4 to 15 only and check for a square matrix on input. Assume only one solution to a board. Let the user have the option of running the program as many times if desired (check input). Output the solved grid with the erased cells with @'s and two spaces between each value. Use any data structure of your choice. Refer to the sample output below. Sample Run: Enter the board size: 8 Enter a Hitori puzzle: 4 8 1 6 3 2 5 7 3 6 7 2 1 6 5 4 2 3 4 8 2 8 6 1 4 1 6 5 7 7 3 5 7 2 3 1 8 5 1 2 3 5 6 7 3 1 8 4 6 4 2 3 5 4 7 8 8 7 1 4 2 3 5 6 Enter the board size: 4 Enter a Hitori puzzle: 1 2 5 3 4 2 2 2 3 6 3 5 2 4 5 1 Solved board: @ 8 @ 6 3 2 @ 7 3 6 7 2 1 @ 5 4 @ 3 4 @ 2 8 6 1 4 1 @ 5 7 @ 3 @ 7 @ 3 @ 8 5 1 2 @ 5 6 7 @ 1 8 @ 6 @ 2 3 5 4 7 8 8 7 1 4 @ 3 @ 6 Run again (Y/N)? y Solved board: 1 2 5 3 4 @ 2 @ @ 6 3 5 2 4 @ 1 Run again (Y/N)?
