同问，两个刷哪个好啊 ？ lintcode有时候感觉有点不靠谱。

我个人充了lintcode vip
个人感觉对新手来说，部分模版题目会有中文视频讲解，这正是我需要的。
同时，lintcode有按时间分配的公司ladder题组。我感觉也可以按照那个刷。
可能对于老手或者很熟练的人，用leetcode看discussion就好。

总的来说，感觉leetcode的community大些，中国人外国人都有，各种support多些；lintcode也是好平台，只是就用户来说可能没有leetcode这个多元

我觉得lintcode主要是corner case不全面

主意不错，但是光比较title的错误率蛮高的，如果有办法比较题目文字就好了

好多题对不上，还是谢谢

楼主好人啊太方便了 谢谢

很棒，谢谢楼主分享！

谢谢楼主费心总结并且分享，这个有的时候很有用。

两个code到底刷哪个呢？区别在哪儿

谢谢楼主分享啊。现在只刷了Leetcode。leetcode和lintcode哪个好呢？
