- 题目要求不能使用辅助空间，并且时间复杂度只能是线性的。 - 题目要求不能使用辅助空间，并且时间复杂度只能是线性的。
- 题目为什么要强调有一个数字出现一次，其他的出现两次？我们想到了异或运算的性质：任何一个数字异或它自己都等于0。也就是说，如果我们从头到尾依次异或数组中的每一个数字，那么最终的结果刚好是那个只出现依次的数字，因为那些出现两次的数字全部在异或中抵消掉了。于是最终做法是从头到尾依次异或数组中的每一个数字，那么最终得到的结果就是两个只出现一次的数字的异或结果。因为其他数字都出现了两次，在异或中全部抵消掉了。**利用的性质是 x^x = 0**。 - 题目为什么要强调有一个数字出现一次，其他的出现两次？我们想到了异或运算的性质：任何一个数字异或它自己都等于0。也就是说，如果我们从头到尾依次异或数组中的每一个数字，那么最终的结果刚好是那个只出现一次的数字，因为那些出现两次的数字全部在异或中抵消掉了。于是最终做法是从头到尾依次异或数组中的每一个数字，那么最终得到的结果就是两个只出现一次的数字的异或结果。因为其他数字都出现了两次，在异或中全部抵消掉了。**利用的性质是 x^x = 0**。

# [301. Remove Invalid Parentheses](https://leetcode.com/problems/remove-invalid-parentheses/)
## 题目
Given a string s that contains parentheses and letters, remove the minimum number of invalid parentheses to make the input string valid.
Return all the possible results. You may return the answer in any order.
**Example 1:**
Input: s = "()())()"
Output: ["(())()","()()()"]
**Example 2:**
Input: s = "(a)())()"
Output: ["(a())()","(a)()()"]
**Example 3:**
Input: s = ")("
Output: [""]
**Constraints:**
- 1 <= s.length <= 25
- s consists of lowercase English letters and parentheses '(' and ')'.
- There will be at most 20 parentheses in s.
## 题目大意
给你一个由若干括号和字母组成的字符串 s ，删除最小数量的无效括号，使得输入的字符串有效。
返回所有可能的结果。答案可以按 任意顺序 返回。
说明:
- 1 <= s.length <= 25
- s 由小写英文字母以及括号 '(' 和 ')' 组成
- s 中至多含 20 个括号
## 解题思路
回溯和剪枝
- 计算最大得分数maxScore，合法字符串的长度length，左括号和右括号的移除次数lmoves,rmoves
- 加一个左括号的得分加1；加一个右括号的得分减1
- 对于一个合法的字符串，左括号等于右括号，得分最终为0；
- 搜索过程中出现以下任何一种情况都直接返回
- 得分值为负数
- 得分大于最大得分数
- 得分小于0
- lmoves小于0
- rmoves小于0
