===== From binary to ternary tree =====

Change the default 3d binary tree to a ternary version, a tree with tree instead of two branches.

==== Solution ====

To achieve this, we need to add another branch and explicitly rotate the branches to (0, 120, and 240) degree.

<code java>
public void run3() [
  A(x) ==> F(x) 
    [RH(  0) RU(45) RH(90) A(x*0.8)]  // first branch  
    [RH(120) RU(45) RH(90) A(x*0.8)]  // second branch
    [RH(240) RU(45) RH(90) A(x*0.8)]; // third branch
]
