Home >Backend Development >PHP Tutorial >有1000块钱,3个人按比例分,如何设计比较合理
请教大家一个问题, 具体是问题是这样的,
1、有1000块钱,A B C 3个人分最多可获得的比例 是30% 40% 30%
2、如果A和B两个人分 A 30% B 70%
3、如果B和C两个人分 B 40% C 70%
4、若果只有一个人分 A 最多可以分30%
B最多可以分40%
C最多可以分70%
希望可以用面向对象的思想来实现
这是什么怪帐?
请说清楚点
我的理解....你说最多可分得,说明钱是可以剩余的(若不可剩余,30% 40% 30%这个分配就不对)
$member=array('a','b','c');//$member=array('a','b');//$member=array('b','c');//$member=array('b');$res = allotment(1000,$member);echo "<pre class="brush:php;toolbar:false">";print_r($res);echo "";function allotment($money,$member){ $ms = array('a','b','c'); $abc = array( 'a' => 30, 'b' => 40, 'c' => 30, ); $ab = array( 'a' => 30, 'b' => 70, ); $bc = array(//B 40% C 70% 一共就 110%了,所以c 改为 60% 'b' => 40, 'c' => 60, ); $one = array( 'a' => 30, 'b' => 40, 'c' => 70, ); $same = array_intersect($ms,$member); sort($same); $res=array(); if(count($same)==1){ $data[$same[0]] = $one[$same[0]]; }else{ $plan = join('',$same); $data = $$plan; } $used = 0; foreach($data as $k=>$v){ $rate = rand(1,$v); $res[$k]['rate']=$rate.'%';//百分比 $res[$k]['mon']=$money * ($rate / 100); $used += $res[$k]['mon']; } $res['r'] = $money - $used;//剩余钱 return $res;}
3、如果B和C两个人分 B 40% C 70% 这个应该是 B 40% C 60%吧
<?php$result = assign(1000, 1, 2, 3);print_r($result);$result = assign(1000, 1, 2, 0);print_r($result);$result = assign(1000, 0, 2, 3);print_r($result);$result = assign(1000, 1, 0, 0);print_r($result);$result = assign(1000, 0, 2, 0);print_r($result);$result = assign(1000, 0, 0, 3);print_r($result);function assign($amount, $a=0, $b=0, $c=0){ if($amount==0 || $a==0 && $b==0 && $c==0){ return false; } if($a>0 && $b>0 && $c>0){ return array('a'=>$amount*0.3, 'b'=>$amount*0.4, 'c'=>$amount*0.3); } if($a>0 && $b>0 ){ return array('a'=>$amount*0.3, 'b'=>$amount*0.7, 'c'=>0); } if($b>0 && $c>0){ return array('a'=>0, 'b'=>$amount*0.4, 'c'=>$amount*0.6); } if($a>0){ return array('a'=>$amount*0.3, 'b'=>0, 'c'=>0); } if($b>0){ return array('a'=>0, 'b'=>$amount*0.4, 'c'=>0); } if($c>0){ return array('a'=>0, 'b'=>0, 'c'=>$amount*0.7); }}?>

干掉A和B,C拿走跑路
这个意思?
