TopCoder_SRM_144_DIV2_250_Time

Problem Statement
	Computers tend to store dates and times as single numbers which represent the number of seconds or milliseconds since a particular date. Your task in this problem is to write a method whatTime, which takes an int, seconds, representing the number of seconds since midnight on some day, and returns a string formatted as "<H>:<M>:<S>". Here, <H> represents the number of complete hours since midnight, <M> represents the number of complete minutes since the last complete hour ended, and <S> represents the number of seconds since the last complete minute ended. Each of <H>, <M>, and <S> should be an integer, with no extra leading 0's. Thus, if seconds is 0, you should return "0:0:0", while if seconds is 3661, you should return "1:1:1".
Definition
	Class: Time Method: whatTime Parameters: int Returns: string Method signature: string whatTime(int seconds) (be sure your method is public)
Constraints
-	seconds will be between 0 and 24*60*60 - 1 = 86399, inclusive.
Examples
0)
	0 Returns: "0:0:0"
1)
	3661 Returns: "1:1:1"
2)
	5436 Returns: "1:30:36"
3)
	86399 Returns: "23:59:59"
