Welcome! In today's lesson, we will explore the practical application of string operations and type conversions in C#. These concepts are essential and are utilized in various programming scenarios. We'll look at a real-world example: time parsing. Have you ever wondered how to add a specific number of seconds to a given time? By the end of today's session, you'll be equipped to calculate this using C#. Let's start!

Imagine this: You receive a time formatted as a string in HH:MM:SS, where HH, MM, and SS represent the hour, minute, and second, respectively. Additionally, you are given an integer representing a number of seconds. Your task is to compute the new time after adding the provided seconds and output the result in the HH:MM:SS format.

For example, if the input time is 05:10:30 and the number of seconds to add is 123, the output should be 05:12:33, since 123 seconds convert to 2 minutes and 3 seconds.
