You have 30 seconds to invert a binary tree. Go.
d-did i do it?

Fuck this shit I'll just send a resume to Apple Inc. instead.

best answer
invert(node *root) {
if (*root != NULL) {
swap (root->left,root->right);
invert(node->right);
invert(node->left);
}
}

Assuming binary trees are implemented, that is.

I still don't get why it became such a big deal. Is he famous?

How serendipitous.
>>51430781
That is just sad.
I'm not smart, I study Information Systems in a REALLY shit university in Brazil, we don't even study algorithms and I could solve that, first try.

void invert(node* root){
if(*root != nullptr){
*root->setData(1/root->getData());
invert(root->getRight());
invert(root->getLeft());
}
}
>>51430480
those aren't a tree

Yeah, I get that, the guy is a retard. I just wasn't sure why everybody started talking about it. Apparently he is responsible for some MacOS package manager.

the word right having more letters than the word left is serendipitous? how so?
>>51430975
Interesting... Do you think he just didn't understand a question? Or maybe he was nervous?
>>51431033
>he just didn't understand a question
I think this is the case. "Inverting a binary tree" is vague as fuck. It sounds like they want the tree turned upside-down or restructured in another way. Not just a simple left-right swap of every node's children.

Maybe that's what they were intending. To see if he would ask qualifying questions.
