摘要: Abstract This paper is a study of persistence in data structures. Ordinary structures are ephemeral the sense that change to structure destroys old version, leaving only new version available for use. In contrast, persistent allows access any or new, at time. We develop simple, systematic, and efficient techniques making linked persistent. use our devise forms binary search trees with logarithmic access, insertion, deletion times O (1) space bounds insertion deletion.
