Heapsort, which I described above, doesn't need to know the length in advance.
Have y'all noticed how pretty much all sorting algorithms rely on length?
Are there any sorting algorithms that aren't explicitly aware of the sequence/array length, and instead just happen to produce a sorted array? (i.e. a sorting algorithm that doesn't rely on # or manual length calculations, and doesn't explicitly try to find the boundary where the array ends.)
Even the current Lua sorting algorithm uses the table length. Would be interesting if there was a sorting algorithm about as fast as Lua's current sorting algorithm, but without relying on length.
