in reply to argument """ isn't numeric in numeric gt(>), error

You have been around for a long enough time to know that you can do more work to help us help you better.

Please answer the following questions:

  1. Are you aware that the message is not an error but only a warning? See perllexwarn and perldiag.
  2. What is your input data?
  3. What is line 44?
  4. How does your input data correlate to line 44?
  5. What have you tried to rectify this?

Node Type: note [id://935328]
[oiskuu]: You want to draw the path? $iter = combinations( $TOP_HEIGHT .. $NODE_HEIGHT, $pos); then get the path from the iter, level change at depth x, for(..) $pos += $level_change; something like that
[oiskuu]: yergh, <code> tags... [$top_height .. $node_height]
[Eily]: Discipulus by demonstrate I suppose you mean simulate with perl?
[Eily]: the demonstration itself is fairly easy. The number of paths on a node is the sum of the numbers of paths to the two nodes above (or one node above on the edges of the triangle)
[Eily]: since the value of a node is also the sum from the two nodes above, you just have to demonstrate that the equality is true at the top of the triangle
[Discipulus]: yes Eily, thanks oiskuu but i dont get it.. ;=( maybe I'll ask a SOPW
