I know generating such a set of combinations is time-consuming, so I am trying to have a solution with the best performance among all. Note: I use as an input data set: SEQUENCE(,B1,10,10)but please don't assume the data set can be numbers only, it could be also strings...
Givennpairs of parentheses, write a function to generate all combinations of well-formed parentheses. 翻译: 给定n对括号,写一个函数来生成所有格式正确的括号组合。 For example, givenn= 3, a solution set is: [ "((()))", "(()())", ...
and you want those to be aggregated to one total value per combination

This code clear and nest.Perfect thing is that it add a node in front of the List,So many NULL situation we needn't consider.So in the end we only need to return first->next,It's what we need But this use to new ListNode each time it need toevaluation,It's not solve the input...
