Leetcode 暑期bb班

呢個po應該對喺香港搵工嘅人冇咩幫助

香港公司唔考algo?

Easy 一日十幾題都得
上到medium即刻收皮
佢啲難度分級唔多準
有啲easy都卡到我半日
有啲hard 1粒鐘KO

題外話 stefanpochman / oldcodingfarmer 同 lee215真係好神

Lm

我想問大家做leetcode 係咪唔會import module?

做leetcode時唔需要
不過有基本認知係好事
因為有啲interview用嘅ide本身無import
熟啲會好啲

玩緊個啲咩15日challenge
beginner level 都題題個幾鐘 想喊 仲要係垃圾曲 好後悔讀U個時冇認真學 algorithm
後面個啲topic 直情冇聽過

392. Is Subsequence
Given two strings s and t, return true if s is a subsequence of t, or false otherwise.

A subsequence of a string is a new string that is formed from the original string by deleting some (can be none) of the characters without disturbing the relative positions of the remaining characters. (i.e., "ace" is a subsequence of "abcde" while "aec" is not).

Runtime: 28 ms, faster than 98.23% of Python3 online submissions for Is Subsequence.
Memory Usage: 13.9 MB, less than 43.99% of Python3 online submissions for Is Subsequence.

class Solution:
    def isSubsequence(self, s: str, t: str) -> bool:
        if len(s) == 1 and s not in t:
                return False
        for i in range(0,len(s)):
            if s[i] not in t:
                return False
            t = t[t.index(s[i])+1:]    
        return True

oursky用leetcode黎in

Algo 唔係你學咗就識打

in唔到 我估junior 大約25k 到啦

有一題leetcode 唔識，其餘係test 你vanilla js做web 嘅pattern, 但我係一開始就react, 所以唔係幾明佢想我點做

我leetcode只會import依個

From collections import Counter

一般code test唔比import野

關乜事。學校教既只係intro，真係學 要識寫，就自學 同 實際操題算。

University Education is a joke
