本篇章节讲解PHP实现的简单排列组合算法应用。分享给大家供大家参考，具体如下： 一、问题： 给你一个40斤的西瓜，给3个人分，有多少种分法？ 二、PHP实现代码： $val){ foreach($aa as $v){ foreach($aa as $vl){ $sum = $val+$v+$vl; if($sum == 40){ $bb[$k][0] = $val; $bb[$k][1] = $v; $bb[$k][2] = $vl; } } } } echo ''; print_r($bb); exit; ?> 运行结果如下： Array ( [0] => 1 [1] => 38 [2] => 1 ) [1] => Array ( [0] => 2 [1] => 37 [2] => 1 ) [2] => Array ( [0] => 3 [1] => 36 [2] => 1 ) [3] => Array ( [0] => 4 [1] => 35 [2] => 1 ) [4] => Array ( [0] => 5 [1] => 34 [2] => 1 ) [5] => Array ( [0] => 6 [1] => 33 [2] => 1 ) [6] => Array ( [0] => 7 [1] => 32 [2] => 1 ) [7] => Array ( [0] => 8 [1] => 31 [2] => 1 ) [8] => Array ( [0] => 9 [1] => 30 [2] => 1 ) [9] => Array ( [0] => 10 [1] => 29 [2] => 1 ) [10] => Array ( [0] => 11 [1] => 28 [2] => 1 ) [11] => Array ( [0] => 12 [1] => 27 [2] => 1 ) [12] => Array ( [0] => 13 [1] => 26 [2] => 1 ) [13] => Array ( [0] => 14 [1] => 25 [2] => 1 ) [14] => Array ( [0] => 15 [1] => 24 [2] => 1 ) [15] => Array ( [0] => 16 [1] => 23 [2] => 1 ) [16] => Array ( [0] => 17 [1] => 22 [2] => 1 ) [17] => Array ( [0] => 18 [1] => 21 [2] => 1 ) [18] => Array ( [0] => 19 [1] => 20 [2] => 1 ) [19] => Array ( [0] => 20 [1] => 19 [2] => 1 ) [20] => Array ( [0] => 21 [1] => 18 [2] => 1 ) [21] => Array ( [0] => 22 [1] => 17 [2] => 1 ) [22] => Array ( [0] => 23 [1] => 16 [2] => 1 ) [23] => Array ( [0] => 24 [1] => 15 [2] => 1 ) [24] => Array ( [0] => 25 [1] => 14 [2] => 1 ) [25] => Array ( [0] => 26 [1] => 13 [2] => 1 ) [26] => Array ( [0] => 27 [1] => 12 [2] => 1 ) [27] => Array ( [0] => 28 [1] => 11 [2] => 1 ) [28] => Array ( [0] => 29 [1] => 10 [2] => 1 ) [29] => Array ( [0] => 30 [1] => 9 [2] => 1 ) [30] => Array ( [0] => 31 [1] => 8 [2] => 1 ) [31] => Array ( [0] => 32 [1] => 7 [2] => 1 ) [32] => Array ( [0] => 33 [1] => 6 [2] => 1 ) [33] => Array ( [0] => 34 [1] => 5 [2] => 1 ) [34] => Array ( [0] => 35 [1] => 4 [2] => 1 ) [35] => Array ( [0] => 36 [1] => 3 [2] => 1 ) [36] => Array ( [0] => 37 [1] => 2 [2] => 1 ) [37] => Array ( [0] => 38 [1] => 1 [2] => 1 ) )更多关于PHP相关内容感兴趣的读者可查看本站专题：《》、《》、《》、《》、《》及《》 希望本文所述对大家PHP程序设计有所帮助。 （编辑：广西网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
