Givennpairs of parentheses, write a function to generate all combinations of well-formed parentheses. For example, givenn= 3, a solution set is: "((()))", "(()())", "(())()", "()(())", "()()()" Solution: 1public
vector<string> generateParenthesis(intn) { res.clear();stringtmp;if(n==0)returnres; dfs(n,0,0, tmp);returnres; } };
