Answer 1

using System;

class Program

    static void Main() {
        string str = "12:14:36";

		List<string> time_parts = new List<string>();
		int pos = 0;

		while ((pos = str.IndexOf(":", pos, StringComparison.Ordinal)) != -1) {
			time_parts.Add(str.Substring(0, pos));
			str = str.Substring(pos + 1);
		}
		time_parts.Add(str); // Add the seconds

		if (time_parts.Count != 3) {
			Console.WriteLine("Invalid time format");
		}

		int hours = int.Parse(time_parts[0]);
		int minutes = int.Parse(time_parts[1]);
		int seconds = int.Parse(time_parts[2]);

		Console.WriteLine(hours + ":" + minutes + ":" + seconds);
    }
