Trie
樹的data structure,用在字串的檢索
複雜度:
m:字串的長度
n:字串的數量
**1.Binary Search
-->Time complexity :Construct complexity : O\(m\*n\*logn\) Search complexity : O\(m\*logn\)
-->Space complexity:
O\(m\*n\)
2.Trie:O(m)
-->Time complexity :Construct complexity : O\(m\*n\) Search complexity : O\(m\)**
**-->Space complexity:
O\(m\*n\)**
