In computer science , a B-tree is a self-balancing tree data structure that maintains sorted data and allows searches, sequential access, insertions, and deletions in logarithmic time. The B-tree generalizes the binary search tree , allowing for nodes with more than two children. It is commonly used in databases and file systems. B-trees were invented by Rudolf Bayer and Edward M. McCreight while working at Boeing Research Labs , for the purpose of efficiently managing index pages for large random access files. The basic assumption was that indexes would be so voluminous that only small chunks of the tree could fit in main memory.

In BST you just traverse both of them in-order, store the keys into an array, then merge the arrays and build a perfectly balanced BST out of the sorted array od keys. But I don't really know how to build a tree out of a sorted array of keys, since a perfectly balanced BST is often not a correct tree. One of my ideas was to build the perfectly balanced BST and then try to move the keys from the last incomplete layer up the tree.
