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: [ "((()))", "(()())", "(())()", "()(())", "()()()" ] 根据题…

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…

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