I've attached my solution, includes part 1 and 3.

I wanted to play with DVRs + recursion. My only complaint with LabVIEW in this case is you cant have a DVR of a typedef in the typedef itself. You have to cast it to a different type (Int32 in this example).

For example in C you can do something like:

struct Node {
int data;
Node** children;
}

Instead you have to do something like

struct Node {
int data;
void** children;
}

and handle the proper typecast outside the typedef.

Also Bpk9p4 you picked the hardest one on my list!
