Node Status?
node history
Node Type: note [id://1008474]
[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
