Re^3: How to get this not the usual round robin looping

This is good, but can be considerably simplified: H1 => [1, 10, 11, 20, 21],

hmm, OP has H1-> 1,8,9

Weird question :)( i need this sequence ... imagine the equation which I won't tell you )

My reply was addressed to kcott, not the OP, and so I used kcott’s dataset.

I thought the same at first, but if you lay out the sequence, the pattern becomes obvious when you read vertically:

{
  H1 => [1, 8,  9],
  H2 => [2, 7, 10],
  H3 => [3, 6],
  H4 => [4, 5]
}

Discipulus, in the Chatterbox, identified it as an example of Boustrophedon, which seems like a pretty good description. :-)

{
  H1 => [1, 8, 9],
  H2 => [2, 7, 10],
  H3 => [3, 6, 11],
  H4 => [4, 5, 12],
  H5 => [13, 20, 21],
}

The difference is because the OP only had H1-H4, while the post with the simplified version added an H5, making the loop longer.


Problems? Is your data what you think it is?
