Hours, Minutes, and Seconds

Split a duration into hours, minutes, and seconds. Write units as h, m, and s, in that order, with one space between units. Omit any zero-valued unit, except that zero seconds is written as 0s.

Implement format_duration(seconds).

Input

seconds: The total duration in seconds.

Output

Return the formatted duration, for example 2h 2m 5s.

Restrições

0 ≤ seconds ≤ 1,000,000,000. Hours may exceed 23; this is a duration, not a time of day.
