What’s the pattern here? I’m a low IQ retard hence cant figure it out

For one, on a logarithmic graph the line approaches a straight line, which is counterintuitive
It exhibits formal system-like behavior, like always “decaying” into a sequence of 92 specific subsequences that never interact with each other, no matter what the starting input string is
It’s also proven that no number greater than 3 will ever appear as the sequence grows

damn, tried this before looking into comments. I didn't know the Conway sequence. the last thing I didn't try is the order of digits. Is there a way to describe this non-verbally?

Holy fuck, Anon! I now realize that this was probably what was given to me as a riddle at a party in my uni freshman year. Everyone was watching as I failed miserably for like 20 min.

good job outing yourself as a retard you fag

string is the correct datatype here. if you used a long integer type (assuming a 64 bit computer) you would get an integer overflow as soon as n > 9. Your low IQ prevented you from seeing this. lmfao.
