I think I get what you're saying, but there are cases where you can't replace that branch with a leaf easily and elegantly
Can you think of one? Rather than the condition being returned in validate() it would just be an if statement within execute().
Thats like saying if you have a leaf in a tree (by definition a node without children), this leaf needs two leafs as children. It doesnt make sense to me --- Double Post Merged, Feb 21, 2017, Original Post Date: Feb 21, 2017 --- Gl with that if the subtree is fairly complex
That's not what it's like saying at all. --- Double Post Merged, Feb 21, 2017 --- I mean don't get me wrong I'm not against the idea, I just haven't come across a use case.
Yes it is, you are saying that null children should be replaced with leafs. Well leafs are defined by having no/null children.
No, I'm saying if you have a branch with one child, the branch and child should be consolidated into a leaf node.
