问题描述
在我看来，前序遍历和 DFS 与我们以深度方式遍历到叶节点的两种情况相同.如果我错了，有人可以纠正我吗?
It seems to me like Pre-order traversal and DFS are same as in both the cases we traverse till the leaf node in a depth wise fashion. Could anyone please correct me if I am wrong?
提前致谢！
推荐答案
预购是 DFS 的一种.
Pre-order is one type of DFS.
深度优先遍历有前序、中序和后序三种.
There are three types of depth-first traversal: pre-order, in-order, and post-order.
