Web面试题 04.10. 检查子树 - 检查子树。你有两棵非常大的二叉树:t1,有几万个节点;t2,有几万个节点。设计一个算法,判断 t2 是否为 t1 的子树。 如果 t1 有这么一个节点 n,其子树与 t2 一模一样,则 t2 为 t1 的子树,也就是说,从节点 n 处把树砍断,得到的树与 t2 完全相同。 WebFeb 26, 2010 · Counterexample: 3 / \ 2 4 / \ 1 5. Now, to get the largest subtree that is a BST, consider this tree: 3 / \ 2 4 / \ 1 5. The inorder-traversal is 1 2 5 3 4. I think you can solve your original problem by finding the maximum-length sorted contiguous subsequence in the inorder-traversal.
