Assume I have a function
evenOut($array, $limit){
//returns exactly $limit items
}
and this data
$animals = array();
$animals['barn'] = array_fill(0,20, 'b');
$animals['forest'] = array_fill(0,20, 'f');
$animals['house'] = array_fill(0,20, 'h');
$animals['mountain'] = array_fill(0,20, 'm');
I want to return a maximum of 10 animals, however they should be spread out evenly among the locations they come from.
so if i did
evenOut($animals,8); i'd get 2 of each('b','b','f','f','h','h','m','m',)
evenOut($animals,2); should return ('b','f')
if I have this data
$animals = array();
$animals['barn'] = array_fill(0,1, 'b');
$animals['forest'] = array_fill(0,3, 'f');
$animals['house'] = array_fill(0,8, 'h');
$animals['mountain'] = array_fill(0,1, 'm');
evenOut($animals,8); expected result would be ('b','f','f','f','h','h','h','m',)
evenOut($animals,10); expected result would be ('b','f','f','f','h','h','h','h','h','m',)
$animals = array();
$animals['barn'] = array_fill(0,0, 'b');
$animals['forest'] = array_fill(0,3, 'f');
evenOut($animals,10); expected result would be ('f','f','f')
I'm not sure how I should approach this, I am hoping there is a simple way
