2-3-4 Trees. Our next self-balancing tree is called a 2-3-4 tree (or a B-tree of order 4), so called because nodes can have anywhere from two to four children. Regular binary search trees can't always be perfectly balanced - that's why AVL trees have to allow the flexibility that subtree heights can differ by at most 1. But because 2-3-4 trees allow nodes to have 2, 3, or 4 …

The simplest possibility to delete an element is to just leave the element there and mark it as "deleted", adapting the previous algorithms so that deleted elements are ignored. Deleted elements can then be re-used by overwriting them when performing an insertion later. However, the drawback of this method is that the size of the tree does not decrease. If a large proportion of the elements of the tree are deleted, then the tree will become much larger than the current siz…

### 2-3-4 Tree Delete Example

Deleting an element in a 2-3-4 tree assumes we will grow (merge) nodes on the way down. The idea is intuitive, but writing the algorithm down in English seems to make it look/sound harder than it is. Again, when dealing with trees, there are different cases.
