This problem is mainly to study the programming logic, we must distinguish the odd number of empty bottles and even several empty bottles, as well as the conditions to terminate the cycle. int main () { int _bottle = 0;//Empty bottle is an odd number, which means the remaining bottle int money =; int count = 0;//Total soda number int bottle=0;//empty bottle number if (Money > 0) { count = money; Bottle = money; } while (bottle!=

The requirements are as follows: There are 2 objects with the same ID, but their values are different. The property value of one of the objects to use for another object. 2 objects with the same ID cannot be present in the Sessionfactory (). GetSession of Hibernate. So come up with a copy of the object. Looking for a lot of places, found that there are 2 ways

It enables applications with tens of thousands of independently computed computer and petabyte-scale data.　　　　　Hadoop historyHadoop was formally introduced by the Apache software Foundation as part of Lucene's sub-project Nutch in the fall of 2005. It was inspired by Map/reduce and Google File System (GFS), which was first developed by Google Lab.In March 2006, Map/reduce and Nutch distributed File System (NDFS) were included in

Bandwidth, transmission speed, two bytes, killing people, always confused which is bit, which is byte, the network speed is 10 m, M indicates bit or byte Article Article Record that Mbps is actually a bandwidth unit, not a speed unit. In Mbps, "B" refers to "bit )". The actual speed unit is MB/s, where "B" refers to "Byte (bytes )". Because data is transmitted by byte, not by bit. Because the two big and lowercase "B" and "B" are different, the two units are not only not the same, but also far
