SRM 144DIV2 200 C++

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, ifseconds is 0, you should return "0:0:0", while if seconds is 3661, you should return "1:1:1".

Definition

 Class:TimeMethod:whatTimeParameters:intReturns:stringMethod signature:string whatTime(int seconds)(be sure your method is public)

Limits

 Time limit (s):2.000Memory limit (MB):64

Constraints

-seconds will be between 0 and 24*60*60 - 1 = 86399, inclusive.
