For each field, print the message Field #x: on a line alone, where x stands for the number of the field starting from 1. If there is a score for the problem, this will be … and mine squares by ``*,'' both without the quotes. The input of the constrained counting problem also includes the total number of mines. Solutions: 1. There must be an empty line between field outputs. Propose an algorithm for solving the game when solvable, with emphasis on CPU time. The goal of the game is to find where all the mines are located within a M x N field. After you submit a solution you can see your results by clicking on the [My Submissions] tab on the problem page. The counting problem was proved to be #P-complete [2]. Kaye studied the following strategy: To determine whether a background square is free we can mark it as a mine. by quickgrid. This will be good practice using recursion and much more elegant than what you have now. and mine squares by ``*,'' both without the quotes. 1*10 .... 1110. 3. as a problem, the Minesweeper counting problem (called #Minesweeper in [2]). The 4 x 4 field on the left contains two mines, each represented by a ``*'' character. of 8 adjacent squares to check, so given a Minesweeper grid with n squares, the runtime will be at most 8t n (where t is the amount of time necessary to check one square’s adjacent partner). In fact, he named the problem minesweeper consistency problem, but we pre-fer to use MINESWEEPER. If we represent the same field by the hint numbers described above, we end up with the field on the right: The input will consist of an arbitrary number of fields. The game shows a number in a square which tells you how many mines there are adjacent to that square. Minesweeper is NP-Complete. Code duplication. In terms of minesweeper, when the user selects a square, the flood fill algorithm clears all squares NOT containing a mine until hitting the edge of the board. Have you ever played Minesweeper? * Ask us, what you want? The game consists of clearing all the squares of a two-dimensional arrangement that do not hide a mine.

The game shows a number in a square which tells you how many mines there are adjacent to that square. Each square has at most eight adjacent squares. The problem mainly deals with changing channel in tv using only up and down button. If the resulting configuration is inconsistent (MINESWEEPER solution is … Each of the next n lines contains exactly m characters, representing the field. THIS IS NOT MY USUAL CODING STYLE, IT IS A QUICK AND DIRTY ONE FOR PROGRAMMING CONTESTS. There must be an empty line between field outputs. This problem(Minesweeper Master) has been asked in Google Codejam qualification round 2014. My Tried Solution: So for the solution, you need to make sure that each non-mine node is in a 3x3 matrix with other non-mine nodes, or a 3x2 or 2x2 matrix if the node is on an edge of the grid; lets call this a 0Matrix. Python solution for Problem C. Minesweeper Master - Google Code Jam 2014 - minesweeper_master.py You can start with a few rules and then go from there. So any node in a 0Matrix have all non-mine neighbors. Its fairly straight forward to generate situations in minesweeper that are not solvable without taking a guess. Minesweeper Consistency is NP Hard Solving Technique: Given a mine field that is a matrix / 2D array, produce an output that contains count of adjacent mines for each squares. Below are the possible results: Accepted Your program ran successfully and gave a correct answer. Given a board with mine locations figure out where the number of mines there should be in each box. The next n lines should contain the field with the ``.'' The need to put this method into this interface may indicate a design problem somewhere else in your program. The first line of each field contains two integers n and m ( 0 < n, m100) which stand for the number of lines and columns of the field, respectively. Restart the app and try to sign in again. Consistency is a decision problem which asks whether a Minesweeper con guration is consistent. Summary [].
