I found a ThoughtWorks interview question at work today. Let me share it.

It can accept any number of special numbers (excluding 0) and output (1~xxx) in any number range. In fact, you can also use the strategy mode to make the algorithm independent. I won’t write about this topic yet (lazy~~)

 private $_special=array();
 private $_words=array();
 public function __construct(array $special,array $words){
 if(in_array(0 ,$special)){
 exit('Special numbers cannot contain 0');
 }
 $this->_special=$special;
 $this->_words=$words;
 }
 public function run( $num){
 $output='';
 for($i=1;$i<=$num;$i++){
 $output.=$this->_calculate($i);
 }
 echo $output;
 exit();
 }
 private function _calculate($number){
 $str='';
 if(strpos($number,$this->_special[0]) > 0){
 return $this->_words[0]."";
 }
 foreach($this->_special as $k=>$v){
 if($number%$v === 0){
 $str.=$this->_words[$k];
 }
 }
 return $str==''?$number.'': $str.' ';
 }
}

$special=array(3,5,7);
$words=array('Fizz','Buzz','Whizz');
$obj=new FizzBuzzWhizz($special,$ words);
$obj->run(100);
