楼主我也是在刷九章ladder，要不要来加个微信交流一下

好啊 已PM

8/28
突然发现lintcode上面题目难度比leetcode标的底，很多lintcode上的medium题在leetcode上是hard

今天开始刷leetcode，按照AC率刷：
771. Jewels and Stones (E)
709. To Lower Case (E)
--------------------------------------------------------------------------------------------
9/1 update: 觉得还是按照类型刷比较合理

8/29
807. Max Increase to Keep City Skyline  (M)
804. Unique Morse Code Words (E)

楼主厉害了！ 感觉刷题还是按类型会容易点，刷几次以后见到类似的能做出来，不然意义不大呀
