Seconds to Clock Time

A stopwatch stores elapsed time as a single number of seconds, but people read `H:MM:SS`. Write `format_duration(total_seconds)` that returns the time as hours, minutes and seconds separated by colons. Minutes and seconds always have two digits; hours have no padding and may be larger than 23.

Input format

`total_seconds`: a non-negative integer.

Output format

A string in the form `H:MM:SS`.

Examples

Input: total_seconds = 3661

Output: "1:01:01"

3661 seconds is 1 hour, 1 minute and 1 second.

Input: total_seconds = 59

Output: "0:00:59"

Less than a minute: 0 hours and 0 minutes.

Constraints

0 <= total_seconds <= 10^9
