both the array-backed implementation and the tree-backed implementation requireO(n+M)where n is the number of words in the dictionary and M is the bytesize of the dictionary, i.e. the sum of the length of the s
Java双数组Trie树的实现方案总结 传统的Trie实现简单,但是占用的空间实在是难以接受,特别是当字符集不仅限于英文26个字符的时候,爆炸起来的空间根本无法接受。 双数组Trie就是优化了空间的Trie树,原理本文就不讲了,请参考An Efficient Implementation of Trie Structures,本程序的编写也是参考这篇论文的。 关于几点论文...

* However this optimization makes the implementation a bit more complex. * For instance if a key "first" is added in the above radix tree, a * "node splitting" operation is needed, since the "foo" prefix is no longer * composed of nodes having a single child one after the other. Thi...
