会是o(n)
queue的长度是不定的，最大长度等于树的宽度，不是高度(深度）。题目中只说是
binary tree。如果是complete binary tree, 应该是n/2。
也许我的表达方式不对，准确地应该是
time complexity O(bxd)
space complexity O(b)
where b is the breadth of the tree, and d is the depth of the tree.
但是BFS一般都是写时间O(V + E) and 空间O (V)。实际上我对这个空间O (V)也不是太
明白，因为显然queue不用把所有节点都装进去。我个人以为这是考虑最坏情况。
因为这个题的数据结构不是图，是二叉树，不用管V，我想了几秒钟就还是写了O(n), O
(n).
反正现在已经绕糊涂了。 |
