## Inorder Traversal is a recursive method whereby we visit the left subtree.

Removing an Element from a B-Tree: Loose removal rule: Loose removal allows to leave a root that has one element too few. public boolean remove(int target) { answer = looseRemove(target); if ((dataCount == 0) && (childCount == 1)) Fix the root of the entire tree so that it no longer has zero elements; return answer;}.

### If you push delete, this will be the action triggered when you push enter.

Degree = 4. Max. Degree = 5. Max. Degree = 6. Max. Degree = 7. Preemtive Split / Merge (Even max degree only). Algorithm For deletion in b tree 1. B-Tree-Delete-Key(x, k) 2. if not leaf[x] then 3. y ← Preceding-Child(x) 4. z ← Successor-Child(x) 5. if n[y] > t − 1 then 6.

Degree = 4: Max. Degree = 5: Max. Degree = 6: Max. Degree = 7. May 31, I found this website that lets you insert and delete items from a B-tree and shows you visually what the B-tree looks like: java b-tree.

I'm looking for another website or program similar to this. This site does not allow you to specify a B-tree of order 4 (4 pointers and 3 elements), it only lets you specify B-trees with an even number of.

Remove(v) runs in O(h) where h is the height of the BST. Removal case 3 (deletion of a vertex with two children is the 'heaviest' but it is not more than O(h)). As you should have fully understand by now, h can be as tall as O(N) in a normal BST as shown in the random 'skewed right' example above.
