Insertion, deletion or replace of any one character are all considered as one change. 【解答】规则很容易理解: 6~20 个字符; 必须包含小写字符、大写字符和数字; 不能包含连续三个相同字符。 但是困难的地方在于,题目不是问一个字符串是否符合条件,而是要求怎样通过最少的增删改来使得密码符合规则。题目类似...
给定一个二叉搜索树的根节点 root 和一个值 key,删除二叉搜索树中的 key 对应的节点,并保证二叉搜索树的性质不变。返回二叉搜索树(有可能被更新)的根节点的引用。 一般来说,删除节点可分为两个步骤: 首先找到需要删除的节点; 如果找到了,删除它。 示例1: 输入:root = [5,3,6,2,4,null,7], key = ...
