Answer 1

I made it automated; i didnt use classes but it is easily able to be converted.

$maxPRoductInRange){
            //create bigger range chart
            makeRangeChart($min,$max,$rangeChart);
            calculateRange();
        } 

    }
}
}


function checkProductCount($min,$max,$priceList){
    global $chart;
    $count=0;
    $rest=0;

    foreach( $priceList as $price){
        if($price>=$min && $price<$max) { 
            $count++; 
        } else { $rest++; }

    }
    $chart[$min]=$count;

    return array($count,$rest);
}


function makeRangeChart($min=0,$max,&$rangeChart){
    $middleOfRange=($max+$min)/2;
    $rangeChart[]=$min;
    $rangeChart[]=$middleOfRange;
    $rangeChart[]=$max;
    $rangeChart=array_unique ($rangeChart);
    sort($rangeChart, SORT_NUMERIC );
}

function printChart(){
global $chart,$highestPrice;

$minPrices=array_keys($chart);
$count=count($minPrices);
$line='';
    for($a=0;$a<$count;$a++){
        $line.=$minPrices[$a];
        $line.=(isset($minPrices[$a+1]))?' - '.$minPrices[$a+1]:'+';
        $line.='('.$chart[$minPrices[$a]].')
';
    }
return $line;
}

calculateRange();
echo printChart();
?>
