**Well done Carlle!**

AHHHH! WHAT IS THIS CODE???

```c
static AATree delete(AATree t,
int key) {
if(t == NULL) return NULL;
if(key < t->key) t->left = delete(t->left, key);
else if(key > t->key) t->right = delete(t->right, key);
else
if(t->left == NULL &&
t->right == NULL) { free(t); return NULL; }
if(t->left == NULL) { AATree l;
l = t->right;
while(l->left != NULL)
l = l->left;
t->key = l->key;
t->data = l->data;
t->right = delete(t->right, l->key); }
else { AATree l;
l = t->left;
while(l->left != NULL)
l = l->right;
t->key = l->key;
t->data = l->data;
t->left = delete(t->left, l->key);
}
if(t->left != NULL &&
t->right != NULL) { int lvl = min(t->left->level, t->right->level) + 1;
if(lvl < t->level) { t->level = lvl;
if(t->right != NULL &&
lvl < t->right->level) t->right->level = lvl;
}
}
```

I will not even...

Keep it up!

The issue only presents a C delete function and informal criticism; it names no file, test, or requested change. Clarify the intended refactor, then locate the implementation and relevant tests before defining what done means.
