Guesstimate is a delightful first draft of a tool to help clarify why we don’t know the answer to your question. Here for example the user has tried to get a handle on how: “Taking down the tree, how long?”
I was a bit taken aback that my immediate reaction to this. A flashback to Simula. What a lovely language. I used back in the late 1960s, and then once more in the mid 70s. It had things that didn’t become common in other languages for a long long time, like threads and classes. It was very good at this kind of computation. Simulation accounted for a big slice of all computing, back in the day.
I didn’t see any loops.
