Re: [閒聊] 每日leetcode

想法差不多 但我一開始最後面只判斷個數沒檢查index (就是直接return star.Count>=left.Count) 想說為什麼都過不了 修正之後就過了 大神好強 C# code: public class Solution { public bool CheckValidString(string s) { var left = new Stack<int>(); var star = new Stack<int>(); int length = s.Length; for (int i=0; i<length; i++) { if (s[i] == '(') { left.Push(i); continue; } if (s[i] == '*') { star.Push(i); continue; } if (left.Count > 0) { left.Pop(); continue; } if (star.Count > 0) { star.Pop(); continue; } return false; } if (left.Count > star.Count) return false; while (left.Count != 0) { if (left.Pop() > star.Pop()) return false; } return true; } } -- (づ′・ω・）づ --
