I want to create an new array with duplicated MAX value from an array
and put other duplicate value in an other array 

```
      $etudiant = array ('a'=>'2','b'=>'5', 'c'=>'6', 'd'=>'6', 'e'=>'2');

```

and i want this result 

```
     $MaxArray =  array ('c'=>'6', 'd'=>'6');
     $otherarray1 =  array ('a'=>'2', 'e'=>'2');

```

Thank you !
