Think for a while, actually find the maximum number of repeated elements can be, because the same person must not share one, so the minimum is the maximum number of repetitions, the same as the previous question,

Multiply hash:This kind of hash function takes advantage of the non-correlation of multiplicationint Hash (char *str){int seed = 131, value=0;while (*str! = ')} {Value = value*seed+ (*str++);}Return value0x7fffffff;}The multiplier used here is 131, and the recommended multiplier is 1313, 13131, 131313, etc.In addition to multiplying by a fixed number, the common ones are multiplied by a constantly changing number, such as:int Hash (char *str){int B = 378551, a = 63689;int hash = 0;while (*str! =

Function Introduction POSTGRES-XC/XL/X2 is an open source project. It provides a multiple-master synchronous, transparent, PostgreSQL cluster solution. Unlike other cluster tools, it has a strong scalability when writing data, and introduces the concept of cluster environment with multiple master architectures. Multi-master means that when writing data, it is no longer subject to a single master node and will be well improved in writing speed. POSTGR

Question connection: http://acm.hdu.edu.cn/showproblem.php? Pid = 1, 1800 It means there are several pilots who need to practice flight on a broom. Each pilot has a different level, and a high level pilot can be a teacher of a low level pilot, each pilot has at most one teacher and only one student. Pilots with relationships between teachers and students can practice on the same broom, and this property is passed. That is to say, if there are five pi

, has no teacher is also legal. Similarly one soldier can has only one StUdent at the most and have no student is also possible. Teacher can teach his student on the same broomstick. Certainly, all the soldier must has practiced on the broomstick before they fly to the mars! Magic broomstick is expensive! So, can-you-help PPF to calculate the minimum number of the broomstick needed.For example:There is 5 soldiers (A B C D E) with level Numbers:2 4 5 6 4;One method:C could teach B; B could teach
