hard部分,很多题没有思路,需要看Discuss。 刷题节奏大概是easy阶段每天12道,medium阶段一天能做8道,hard阶段随缘2~4道。(早八点到下午六点,中间只有吃饭没别的活动了,晚上跟着ucb的cs61b学学java)每道题AC后,会检查运行时间。慢的话就去discuss上学习大神们的解法思路,然后自己写一遍提交。查看discuss的情况还包...
当然有时候我们会牺牲空间换取时间,比如在动态规划中状态的保存,或者是记忆化搜索,避免在递归中计算重复子问题。 213. House Robber II 的 一个Discuss 会教我们如何用记忆化搜索减少程序执行时间。 语言:各有千秋 对一个问题来说,解题逻辑不会因编程语言而不同,但是具体coding起来语言之间的差别还是很大的。用不...
