Givennpairs of parentheses, write a function to generate all combinations of well-formed parentheses. For example, givenn= 3, a solution set is: "((()))", "(()())", "(())()", "()(())", "()()()" 本题的关键在于发现规律,如下: n=1() n=2 (f(1)),f(1)+f(1) n=3...
Givennpairs of parentheses, write a function to generate all combinations of well-formed parentheses. For example, givenn= 3, a solution set is: "((()))", "(()())", "(())()", "()(())", "()()()" 解题思路: 利用递归的思想。用left和right分别记录剩余的左,右括号数。 每次都...
