(Python/Java/C++/C/Go/JS/Rust) 答疑问:是什么原因导致了这两种算法的快慢?答:我用「获取了多少信息」来解释。暴力做法每次拿两个数出来相加,和 target 比较,那么花费 O(1) 的时间,只获取了 O(1) 的信息。而哈希表做法,每次查询都能知道 O(n) 个数中是否有 target−nums[j],那么花费 O(1) 的...

350+Problems / 1000+Solutions 最好不要满足于accept,要追求最高效率。做一题就要杀死一题。leetcode不是给了运行时间的分布吗,基本上每个波峰都代表了一种特定复杂度的算法,中间的起伏体现的就是具体实现细节的差距。每次都要向最前面的波峰努力啊>.<。追逐最前一个波峰的过程不但锻炼算法,还锻炼数据结构,锻炼...
