Hi, nice article, but i think you shouldn’t misuse the try/catch

public Double InternalParseInput(String inputString)
{
Double doubleValue;

if (Double.TryParse(inputString, out doubleValue))
return doubleValue;
else
return default(Double);
}

Actually, for your example: For the first pass, both the fast and the slow pointers will meet at D to detect the presence of the loop. Here’s the path that they’ll follow:

Slow: A -> B -> C -> D
Fast: A -> C -> E -> D

Now, when you reset the slow pointer to the beginning, and move them one node at a time, they’ll follow the patterns as below:

Slow: A -> B -> C
Fast: D -> E -> C

Are you sure this works for all cases?
Assume the case that you started out with namely:
A -> B -> C -> D -> E -> C
When you increment the slow pointer by one and the fast pointer with two, they will eventually meet at E (n and 2n as you later describe).
Now if you set the slow pointer to A and let the fast pointer be and start incrementing them one node at a time they will follow the pattern as below:
Slow: A -> B -> C -> D -> E
Fast: E -> C -> D -> E -> C

Please correct me if I got anything wrong.
