vipkid 大数据开发笔试编程题
题目很简单,编程的第一个sql只有50%通过率,交了卷问了牛客AC的大佬才知道除了分数排名还要考虑交卷时间。
还是自己没考虑全面,发帖当作一个教训吧。
贴一下两个题的代码:
第一题:
select st_id,st_name from (select *,sum(score) as sum_score, strftime ('%s', max(start_time)) - strftime('%s', min(start_time)) as use_time from S group by st_id order by sum_score,use_time) limit 1
第二题:
s=input().split() s[-1]+="," count=0 res=[] for i in s: if "-"+i in s and i not in res: count+=1 res+=[i,"-"+i] print(count)
