In this paper, we put forward a region representation data structure-digital search tree (DST) and its lineal encoding (LDST).

Throughout the years, many kinds of data structure had been proposed and applied, for instance, hash tables, binary search tree, digital search tree, ternary search tree and so on and so forth.

From digital documents to ramped-up search engines, many library systems can help you find just about anything that can help you with your projects.
