In this little training challenge, you are going to learn about the Robots_exclusion_standard.The robots.txt file is used by web crawlers to check if they are allowed to crawl and index your website or only parts of it.Sometimes these files reveal th…

Your task is simple:Find the first two primes above 1 million, whose separate digit sums are also prime.As example take 23, which is a prime whose digit sum, 5, is also prime.The solution is the concatination of the two numbers,Example: If the first…

2015 UESTC Winter Training #7 2010-2011 Petrozavodsk Winter Training Camp, Saratov State U Contest 据说这套题写出3题就是金牌水平了... Problem D. Group Stage 足球比赛,现在有n(2<= n <=100)支球队.要从中选拔m(1<= m <=n-1)支球队,每支球队互相比赛一场,即比赛n*(n-1)/2场,胜者得3分,平局各得1分.最后从大到小列出排名,如果有…

比赛时候面向过题队伍数目 打表- - 看了题解发现确实是这么回事,分析能力太差.. /* HDU 6063 - RXD and math [ 数学,规律 ] | 2017 Multi-University Training Contest 3 题意: 求 Σ μ(i)^2 * sqrt( n^k/i ) [ 1 <= i<= n^k ] n,k <= 1e18 分析: 首先 μ(i) 为莫比乌斯函数,若 i 是完全平方数的倍数则 μ(i) = 0 ,否则 μ(i) = ±1 所以只有不是…
