Array Manipulation

    My Solution is the similar, but it can not pass testcases 7-13, because "Runtime Error".

    I downloaded input\output data for 7th testcase and it's pass locally.

    What is wrong?

    $handle = fopen ("php://stdin", "r");
fscanf($handle, "%i %i", $n, $m);

$h = array_fill_keys(range(0, $n), 0);
for($a0 = 0; $a0 < $m; $a0++){
    fscanf($handle, "%i %i %i", $a, $b, $k); 
    $h[$a-1] += $k;
    $h[$b] -=$k;     
}
$prev = 0;
$max = PHP_INT_MIN;
 foreach($h as $value){
     $prev += $value;
     if($prev > $max) $max = $prev;
 }
echo $max;
