https://leetcode.com/problems/inorder-successor-in-bst/description/ image.png 这道题如何思考。 我们可以发现,如果根节点的值和P的值一样的时候,下一个值无非就是跟节点右子树的最左端。如果根节点比P大,我们应该去右边找和P一样大的节点。
这道题是之前的那道Inorder Successor in BST的后续,之前那道题给了我们树的根结点,而这道题并没有确定给我们根结点,只是给了树的任意一个结点,然后让求给定结点的中序后继结点。这道题比较好的一点就是例子给的比较详尽,基本覆盖到了大部分的情况,包括一些很 tricky 的情况。首先来看例子1,结点1的中序后继...
