[julia-users] Re: How to make a tree datastructure with vector data in JULIA ?

[Andre Bieler]

I think I start seeing what you want. A few questions:

1) Can the leafs be of the same type as the root and child?
2) Does every child need to have one child at least? (= no child with zero 
leafs)

you can do the following:

```julia

# this generates a list of empty vectors that can hold MyNode types, each 
of these vectors
# will then be filled with leafs
# once all vectors are filled with leafs we can distribute them to the 
children

all_leafs = Any[MyNode[] for i in 1:nChildren]

for i in 1:100
  childIndex = rand(1:nChildren) # pick to which child this leaf will go
  #create your leaf here with necessary stuff like above
  leaf=MyNode(data,level, MyNode[], 0)
  push!(all_leafs[childIndex], leaf)
end
```

then you can distribute those leafs:

```julia

for i in 1:nChildren
  root.child[i].child = all_leafs[i]
end
```
