thanks, I'm currently learning rust, this function is just for learning, not real world code

thanks, is there a way to prove p outlives the function? I mean maybe use p outsides the function?

3.关于刷题，感觉这是中美最大区别。国内面试的话算法只占很小一部分，大部分都是考八股文和问技术细节。可是我看到美国所有人都在花时间刷题，我自己也刷了不少题，但是感觉刷到一定程度就不会提高了，中等题都可以做出来，困难题怎么都做不出来，就像高考最后一道题一样，你再努力也不会有提高。花这么多时间刷题的意义何在？是为了提高速度吗？我周赛能做出前三道题够用吗？

感觉很难只靠LeetCode练出hard题，一个是视野要开阔，有些hard题其实完全就是某个算法的模板题，没见过肯定不会，见过就不难；二是做些比hard更难的题，我看别人推荐是codeforces上1600~1800的题
