2. 3. 4. 5. 6. 7. trie 类似于字典的构造,建立一棵树,每个节点表示一个字母,层深度表示串的长度,把有相同前缀的串放在同一个子树内。可以快速完成多个文本串中匹配一个模式串的任务。 比如这棵trie,打了红色标记就表示有一个串到尾了。所以这棵trie存储了文本串\(abc, abd, abcd, b, bcd, efg, ...
The results show that the best efficiency of solid-state QDSSCs achieved by a bare TiO2/CdS/CdSe electrode is 0.65% (AM 1.5, 100 mW cm2). All the electrodes modified by DIOPA and the dipole molecules, 4-methoxythiophenol (BTOMe) and 4-chlorobenzenethiol (BTCl), showed improved cell ...
