arrays - 如何检查数组中的数字是否包含在嵌套数组中？

问题描述

我正在开发井字游戏，并想检查玩家的选择是否与包含获胜组合的嵌套数组匹配。

目前，例如，[7,8,9] 或 [9,7,8] 或 [1,2,3] 或 [1,3,2] 结束游戏并宣布获胜者，这是他们应该做的。

但是，例如，[1,7,8,6,9] 或 [1,7,3,5,6] 或 [1,4,2,3,9] 将被忽略并且不会宣布获胜者正如预期的那样，尽管数组包括获胜组合“7,8,9”和“3,5,7”和“1,2,3”。

感谢您提前提供任何建议或帮助。

3x3 网格中的所有获胜组合。

WINNING_COMBOS = [[1,2,3],[4,5,6],[7,8,9],[1,4,7],[2,5,8],[3,6,9],[1,5,9],[3,5,7]]

我有两个播放器数组，@@player_one 和 @@player_two 从@possible_choice 数组中选择数字。

@possible_choice = [1,2,3,4,5,6,7,8,9]
.
.
.
def player_one_turn()
  puts "Player One, make your choice:"
  p @possible_choice
  puts @grid
  @@player_one << @possible_choice.delete(gets.chomp.to_i)
  p @@player_one
end

我也有has_won？方法

def has_won?
  WINNING_COMBOS.include?(@@player_one.sort) ||
  WINNING_COMBOS.include?(@@player_two.sort)
end

完整的未完成游戏。请不要介意网格，我仍在努力。


class Grid
    WINNING_COMBOS = [[1,2,3],[4,5,6],[7,8,9],[1,4,7],[2,5,8],[3,6,9],[1,5,9],[3,5,7]]
    attr_accessor :possible_choice
    attr_accessor :grid

    def initialize
        @possible_choice = [1,2,3,4,5,6,7,8,9]
        @grid = "
                |----|----|----|   
                |  1 |  2 |  3 |
                |----|----|----|
                |  4 |  5 |  6 |
                |----|----|----|
                |  7 |  8 |  9 |
                |----|----|----|
                "
    end
end

class Game < Grid
    @@player_one = Array.new
    @@player_two = Array.new

    def game
        puts
        puts "*** This is a tic-tac-toe game for two human players. ***"
        puts
        loop do
            player_one_turn()
            puts
                if has_won?
                    puts "The game has ended. Player One has won!"
                    puts
                    return
                end
            break if @@player_one.length == 5
            player_two_turn()
            puts
                if has_won?
                    puts "The game has ended. Player Two has won!"
                    puts
                    return
                end
        end
    end

    def player_one_turn()
        puts "Player One, make your choice:"
        p @possible_choice
        puts @grid
        @@player_one << @possible_choice.delete(gets.chomp.to_i)
        p @@player_one
    end

    def player_two_turn()
        puts "Player Two, make your choice:"
        p @possible_choice
        puts @grid
        @@player_two << @possible_choice.delete(gets.chomp.to_i)
        p @@player_two
    end

    def has_won?
        WINNING_COMBOS.include?(@@player_one.sort) ||
        WINNING_COMBOS.include?(@@player_two.sort)
    end
end

new_game = Game.new
new_game.game

解决方案

WINNING_COMBOS = [[1,2,3],[4,5,6],[7,8,9],[1,4,7],[2,5,8],[3,6,9],[1,5,9],[3,5,7]]

def win?(player)
  WINNING_COMBOS.each do |x,z,y|
    return true if player.include?(x) && player.include?(z) && player.include?(y) 
  end
  false
end

def has_won?
  win?(@@player_one) || win?(@@player_two)
end

应该做的工作，没有必要对数组进行排序。
