Write a SQL query to rank scores. If there is a tie between two scores, both should have the same ranking. Note that after a tie, the next ranking number should be the next consecutive integer value. In other words, there should be no "holes" be…

D. Memory and Scores   Memory and his friend Lexa are competing to get higher score in one popular computer game. Memory starts with score a and Lexa starts with score b. In a single turn, both Memory and Lexa get some integer in the range [ - k;k] (…

做到这题时卡了不少时间,参考了别人的解法,觉得挺不错的,还挺巧妙. SELECT s2.Score,s1.Rank From ( SELECT S1.Score, COUNT(*) as Rank FROM (SELECT DISTINCT Score from Scores) as S1, (SELECT DISTINCT Score from Scores) as S2 Where S1.Score<=S2.Score Group By S1.Score ) s1 ,Scores s2 WH…

Memory and Scores 题目链接:http://codeforces.com/contest/712/problem/D dp 因为每轮Memory和Lexa能取的都在[-k,k],也就是说每轮两人分数的变化量在[-2k,2k]: 故可以定义状态:dp[times][diff]为第times次Memory和Lexa的分数差为diff的方案数. 而dp[times][diff]可以从dp[times-1][diff-2k]到dp[times-1][diff+2k]转移而来: 又因为变化…
