title: How to insert into a complete B+ tree?
body: <p>I can't find any examples on how to insert into a B+ tree when every position is filled. I have a B+ tree M=5 and L=5 and the tree is complete with values from 1-25 inserted. If I wanted to insert 26 into the tree, how would I go about splitting the tree up so I can accommodate the 26?</p>
