Implement Trie (python 版) bofei yan 懒人解法: 假设只有26个英文字母,每个节点有26个son 查询时遍历待查询字符串 class Trie: # trie node class Node: def __init__(self): self.is_end = False self.v = '' self.son = [None] * 26 def __init__(self): """ Initialize your data struct...

Sie können eine Node-Klasse in Python definieren, um einen Knoten eines Trie zu implementieren, wie im folgenden Beispiel gezeigt. classNode:def__init__(self):self.children=[]foriinrange(26):self.children.append(None)self.isLeafNode=False ...
上图是一棵Trie树,表示一个保存了8个键的trie结构,“A”, “to”, “tea”, “ted”, “ten”, “i”, “in”, and “inn”.。 从上图可以归纳出Trie树的基本性质: 根节点不包含字符,除根节点外的每一个子节点都包含一个字符。 从根节点到某一个节点,路径上经过的字符连接起来,为该节点对应的字符...
