摘要
A double-array is a well-known data structure to implement the trie. However, the space efficiency of the double-array degrades with the number of key deletion because the double-array keeps empty elements produced by the key deletion. This paper presents a fast and compact deletion method using a single-nodes. From simulation results for large sets of keys, new method is about 30 to times faster than old method and keeps high space efficiency.
