Hello Group,

Recently I was asked this question in a technical discussion. What is the longest possible loop that can be written in a programming language? This loop has to be as long as possible and yet not an infinite loop and should not end-up crashing the program (Recursion etc...)

I honestly did not know how to attack this problem, so I asked him if is it practically possible. He said using some computer science concepts, you can arrive at a hypothetical number which may not be practical but nevertheless it will still not be infinite.

Anyone here; knows how to analyse / attack this problem.

P.S. Choosing some highest limit for a type that can store the highest numerical value is apparently not an answer.

Thanks in advance,
