A 2-3-4 Tree is a self balancing b-tree that can have up to 4 nodes within a node/root/leaf.
Steps in 2-3-4 Tree
Put in your nodes into the root.
If a root haves 4 nodes, pre-split it into a root(the middle node) with two child nodes(1 node with the smallest node and the other node with 2 biggest node.
Then add the 5th node and continue and pre-split if needed too.
