// Read an integer value corresponding to a person's age (in days) and print it in years, months and days, followed by its respective message “ano(s)”, “mes(es)”, “dia(s)”.

// Note: only to facilitate the calculation, consider the whole year with 365 days and 30 days every month. In the cases of test there will never be a situation that allows 12 months and some days, like 360, 363 or 364. This is just an exercise for the purpose of testing simple mathematical reasoning.

// Input
// The input file contains 1 integer value.

// Output
// Print the output, like the following example.

$x = intval(fgets(STDIN));

$format = [365, 30, 1];
$types = ['ano(s)', 'mes(es)', 'dia(s)'];

foreach ($format as $key => $day){
    $format_day = floor($x/$day);
    $type = $types[$key];

    echo "$format_day $type\n";

    $x -= ($format_day*$day);
}
