Why would I need to know how to reverse a binary tree to do design verification work?

You should hire me because I have experience at a world leading ASIC design corporation, have been exemplary in simplifying flow of my suites, and am quicker than most others in the field to pick up new tricks and to make use of old tricks to automate my processes and update ancient code.

I can also speak English fluently which is more than I can say for half of the people in this industry

Yeah, I can. You just need to start at the root, and recursively swap the left and right branches.

I think this is right

struct node

node *left, *right;
};

void reverse(node *arg)
{
if (!arg) return;
node *temp = reverse(arg->left);
arg->left = reverse(arg->right);
arg->right = temp;
}

Aaron Bell

honestly, I think this question is worded quite poorly.
A binary tree isn't ordered, so asking someone to reverse it doesn't really make sense.
I think something like "mirror a binary tree" or mentioning that inorder traversal should yield a reversed result would be better fitting.
I'm pretty sure that there's a decent amount of people who get stuck on that. At least I can't imagine so many people having issues with basic recursion.

James Jones

I can't help but think reversing a binary tree is a pointless task but I haven't spent much time on it.
We are talking about swapping the nodes recursively right? Every left becomes a right and vice versa?
In that case we should just have traversal functions predicated on a bool that asks how you wanted the tree to look.

Next to free in execution and memory. Costs some in binary size.

Noah Russell
Noah Russell

If you put conditionals in your function, that fucks branch prediction. If you use two separate functions each for different order, that twice the amount of code and fucks cache.

Austin Moore
Austin Moore

Even ignoring "muh low level efficiency", unless you never want to interface with other software, it's quite likely you'll have to actually modify the tree if the order is relevant to you.

Costs some in binary size
what did he mean by this?

Logan Sanchez
Logan Sanchez

two separate functions for each different order
Obviously.
What kind of idiot would write it any other way?
twice amount of code
fucks the cache
Luckily traversal is not math code. It's rather slim.
But come to think of it there's tons of reasons the compiler might explode the call at (almost) every call site. Which is still probably not enough to be a major problem compared to an actual reversal but it's nowhere near as cheap as the structure that doesn't support a reversal.
Basically what user here mentioned. The code duplication (meta-generated or not) costs you icache and if you have binary size constraints (mainly relevant in embedded) that's a cost too. Of course as user brings up it does cost more in icache.
interface with other software
Depends on what you mean. You normally don't expect binary compatibility between programs.
If we're talking about actually calling the original code (the code where we implemented this scheme for reversal) I don't see any issue.

I don't know what he's talking about.
The only way I could see reversing being useful would be to just have one rotate method but that's just going to be less efficient.

Bentley Cooper
Bentley Cooper

AVL trees is a self balancing tree data structure.
The idea is to reverse small sections of the tree in order to keep the depth of the tree either even or uneven by a single depth.
Eg

         z                                      y 
/ \ / \
y T4 Right Rotate (z) x z
/ \ - - - - - - - - -> / \ / \
x T3 T1 T2 T3 T4
/ \
T1 T2

This, but unironically. Just cast to a struct that has left and right reversed.

Anthony Brown

You need to complete the reverse homework assignment before you get the avl assignment in the first semester course of algorithms and data structures.
Reversing is the most basic form of tree manipulation.

Lucas Cook
Lucas Cook

I guess I wasn't all that specific. I can see how swapping nodes is important for trees. But I don't see how a full reversal (swapping every node) is meaningful.

Of course trees have subtrees though. So I guess it's valid to ask this.

Joseph Baker

Reversing a tree and traversing a tree in reverse direction is the same procedure except for the output. This question is literally just about knowing basic tree traversal.

If you need to pass a tree, there is absolutely no point in traversing the tree and generating an new one based on the return value.
