Continue to the Round 1B 2010. The second question does not understand the question. The third question can be understood, but the algorithm has been tossing for a long time. Let's take a look at the third question first. Given a set S = {2, 3 ,... n}, its subset s' satisfies the nature: n is the k element in s', then k should also be in s', similarly, k is the k' element, so k' should also be in s'. After a finite step, k = 1, not in s', it is called n for s' as a Pure

Sometimes this problem occurs. We need to query a table and sort it by business. For example, I need the following results: Region date fee product no. User No. 290 201202 258 1 S1290 201202 200 1 S5290 201202 100 1290 201202 90 2 S7290 201202 88 2 S9290 201202 10 2 S12. The leader asked me to generate a report and we need to see the top three customers who charge for each business. In this case, using rank () over (partition) is a good choice.

In many cases, we need statistics on the ranking, the most common is the score, the number of votes, and so on. However, before SQL Server 2005, SQL Server 2000 did not provide this direct function for us to use. The same is true for access. Access: Select name, score, (select IIF (isnull (sum (1), 1, sum (1) + 1) from score_rank where score>. score) as rank from score_rank a order by score DESC Web SQL 2000: Select name, score, (sele

PageRank is a link analysis tool and it assigns a numerical weighting to each element of a hyperlinked set of documents, s Uch as the world Wide Web, with the purpose of "measuring" its relative imp

Ranking function three brothers, a look at the name will know, are for the ranking and born! But each has its own characteristics! Here's an example to illustrate the problem! (The following chestnuts do not use the partition by keyword to sort the entire result set)Rank each value a rank, the same value in the same position, such as the first 2, the next value will be third, and so on, as shown in the foll

Update less site ranking is the better, of course, for the industry. Site collection does not need more than 1000, these included quantity is very abnormal. 1 updated information on the rankings do not have much value is not more than the value of the update of the larger, updated content to do outside the chain, not necessarily ranked. Does not update the content does not send the chain, the rank is very stable. Site optimization upfront, your site i

Label:Rank ScoresWrite a SQL query to rank scores. If there is a tie between the scores, both should has the same ranking. Note that after a tie, the next ranking number should is the next consecutive integer value. In the other words, there should is no "holes" between ranks. +----+-------+ | Id | Score | +----+-------+ | 1 | 3.50 | | 2 | 3.65 | | 3 | 4.00 | | 4 | 3.85 | | 5 | 4.00 | | 6 | 3.65 | +----+-------+ For example, given the abo

This article introduces four very interesting functions in SQL. I call it the row-labeled functions row_number, rank, dense_rank, and ntile. Row_number: it adds a row-labeled column to the data table. It is continuous in the data table. We must sort the table in a certain order before using row_number.
