Delete Duplicate Emails
原题leetcode,数据库常用操作去重，思路就是按照email列相同合并后（其实这时候已经去重了）取出ID，从person中删除不存在ID # Select 嵌套使用临时表时，需要为临时表指定别名 a。 # group 默认不会选择最大最小ID，只会选择行靠前的ID delete from person where Id not in (select * from (select min(Id) from person group by Email)as a) DELETE p from Perso

1.过滤邮箱地址
Besides lowercase letters, these emails may contain '.'s or '+'s. Given a list of emails, we send one email to each address in the list. [i].length <= 100 1 <= emails.length <= 100 Each emails[i] contains exactly one '@' character. 初始算法 class Solution: def numUniqueEmails(self, emails: List[str]) -> int: n = len(emails) emails: List[str] :rtype: int """ email_set = set() for email in emails

自定义scala 字符串插值
方法 //见下面的 implicit class EmailHelper val emails = emails"测试${email}测试" emails.filter r implicit class EmailHelper(val sc: StringContext) extends AnyVal { def emails(args: Any { val strings = sc.parts.iterator val expressions = args.iterator val emails1 ::: emails2 } } } 代码解释： 下面一句代码： emails"测试${email}测试" 被编译器重写为： new EmailHelper(new StringContext ("测试", "测试")).emails(email) 字符串插值和scala macro结合起来还可以实现很多功能。
