Replied to a topic by RuLaiFo 程序员 单元测试有必要吗?
如果把 e2e,integration,unit tests 从上往下排起来,有人推荐应该是金字塔形(侧重在单元测试),也有人说应该是棱形(侧重在集成测试),我的经验是如果集成测试框架好,可以多写集成测试,单元测试重点保障关键的 local 逻辑,然后一定要有 coverage tool 这样只要综合的 coverage 够就行了
30 之后记忆力开始变得很差(幸好在这之前毕业了。。),我觉得一方面是年纪的原因,还有一方面可能是睡眠的问题。还有可能是现代生活 /工作太容易被打断,需要进入深度工作状态才行。
其实用堆的话 ,空间复杂度 是 O(k) 时间复杂度是 O(nlogk)
这里的 k 就是 100
已经比 O(nlogn) 小了

如果要找比 O(nlogk) 还少的,那么就只能空间换时间了,可以用 bucket sort
时间复杂度 O(n) 空间复杂度 也是 O(n)

Replied to a topic by MarkLeeyun 算法 关于刷题的那些事
先按照大厂的 tag 题来,然后一边刷一遍查漏补缺,总结模版

总的来说这玩意儿考察两点
1 拿到题目,知道怎么解(算法层面)
2 知道算法,用自己熟悉的编程语言快速实现(实现层面)

先评估一下自己在哪一块比较弱,
如果是 1, 那就多做一些各种类型的题目,拓宽视野
如果是 2,那么就要对于每种类型的题目,总结模版
