Magic subject

一晚上撸了四千字出来,累到爆炸…
感觉如果现在让我穿越回大二,再来一次美赛,一定溜得飞起。
交了论文之后本来想睡个觉的来着,但是周四还有Cryptography & Security要考。
鉴于乌大爷一般不按套路出牌,我觉得还是要抓紧时间复习一下,考好这学期最后一场考试。

Do not expect to have any big improvement within days.
Be patient and over time, you will be surprised at where you are today.
I have tried my best in these days, and I am aware of there are numerous stuff can be learned during this period. With a little bit of luck, I would be different and better after my holiday.

So, see you later:)

Validate IP address

昨天面试了微软北京的组,Coding问了一道判断IP是否合法的问题,然鹅当时脑子打铁,写的完全惨不忍睹,今天早上起床吓得我赶紧重新写了一遍。

class Solution(object):
    def isIPv4(self, s):
            try: 
                return str(int(s)) == s and 0 <= int(s) <= 255
            except: 
                return False
            
    def isIPv6(self, s):
        if len(s) > 4: 
            return False
        try: 
            return int(s, 16) >= 0 and s[0] != '-'
        except: 
            return False

    def validIPAddress(self, IP):
        """
        :type IP: str
        :rtype: str
        """
        if IP.count(".") == 3 and all(self.isIPv4(i) for i in IP.split(".")): 
            return "IPv4"
        if IP.count(":") == 7 and all(self.isIPv6(i) for i in IP.split(":")): 
            return "IPv6"
        return "Neither"
        

Be a survivor of a disaster

这两天全靠红牛和咖啡续命了。

11月1号考完了这学期的第一门Final,在皇家展览馆考的。看了一下考场的座次表,三千人一起考试真的是美滋滋。考场的“服务人员”态度也特别好,看我手画Burndown Chart,就贴心的给我递过来了一把尺子 (可能是看我手画的太惨不忍睹了)。

因为这个暑假有四个月的时间,待在家里的话虽然可以轻松许多,但是还是觉得趁还可以实习,应该多锻炼一下自己。本来以为离放假还有一段时间,打算等考完试再去找实习,但是前两天算了一下日期,我发现再不找实习估计就来不及了,于是赶紧把简历投了起来。运气还不错的是,有好几个大佬都给了机会让我试一试。考完试的第二天,也就是11月2号,我约了微软的面试。正好打算考完试休息放松一天,于是2号就被我完全腾空用来面试了。

Memory

When I was 5 years old, my mom always told me that happiness was the key to life. When I went to school, they asked me what I wanted to be when I grew up. I wrote down “Happy”.

They told me I didn’t understand the assignment and I told them they didn’t understand life.
