生成括号 给定 n 对括号,请写一个函数以将其生成新的括号组合,并返回所有组合结果. 样例 给定 n = 3, 可生成的组合如下: "((()))", "(()())", "(())()", "()(())", "()()()" 解题 参考链接 采用递归树的思想 left: 左括号的数量 right:右括号数量 n:括号的对数 当left == n:表示左括号已经到达最大值了,只能添加右括号 当left &…

9.6 Implement an algorithm to print all valid (e.g., properly opened and closed) combinations of n-pairs of parentheses.EXAMPLEInput: 3Output: ((())), (()()), (())(), ()(()), ()()() LeetCode上的原题,请参见我之前的博客Generate Parentheses 生成括号. 解法一: class Solution…

Given n pairs of parentheses, write a function to generate all combinations of well-formed parentheses. For example, given n = 3, a solution set is: [ "((()))", "(()())", "(())()", "()(())", "()()()" ] 给定一…

生成括号对数 给出 n 代表生成括号的对数,请你写出一个函数,使其能够生成所有可能的并且有效的括号组合. 例如,给出 n =3,生成结果为: [ "((()))", "(()())", "(())()", "()(())", "()()()" ] class Solution { public List<String> generateParenthesis(int n) { List<S…

Given n pairs of parentheses, write a function to generate all combinations of well-formed parentheses. Have you met this question in a real interview?     Example Given n = 3, a solution set is: "((()))", "(()())", "(())()",…

Given n pairs of parentheses, write a function to generate all combinations of well-formed parentheses. For example, given n = 3, a solution set is: "((()))", "(()())", "(())()", "()(())", "()()()" 在LeetCo…

Given n pairs of parentheses, write a function to generate all combinations of well-formed parentheses. For example, given n = 3, a solution set is: [ "((()))", "(()())", "(())()", "()(())", "()()()" ] 题意:…

问题描述:给n对括号,生成所有合理的括号对.比如n=2,(()),()() 算法思路:利用深度优先搜索的递归思想,对n进行深度优先搜索.边界条件是n==0:前面电话号组成字符串也是利用dfs. public List<String> generateParenthesis(int n) { List<String> result = new ArrayList<>(); dfs(result,"",n,n); return result; } pub…

给 n 对括号,写一个函数生成所有合适的括号组合.比如,给定 n = 3,一个结果为:[  "((()))",  "(()())",  "(())()",  "()(())",  "()()()"]详见:https://leetcode.com/problems/generate-parentheses/description/ 由于字符串只有左括号和右括号两种字符,而且最终结果必定是左括号3个,右括号3个…
