Cache a lot of data, but read only a subset of the data, how to handle it? For example, 100 data is saved in the cache, but paging data, such as reading only 10 data per page, is read. In this case, the 100 pieces of data can be divided into 10 times to save them separately. The key for each cache entry requires a special design, such as: 01-10-products, 02-10-products ... How do I avoid caching some of the unwanted data? Like what:public class Teacher{ public int id{get;set;} public st

is the size of the chunk that needs to be allocated.As an example:In a 64-bit system, determine the size of the chunk to 0x88+0x8=0x90. Therefore, each application will be assigned a size of 0x90 chunk.The return of a chunk size of 0x90, in addition to pre_size and size, also left the area of 0x80 size, you will think "what?" I applied for the size of the 0x88, but returned a 0x80 size memory? "In fact, these chunk are virtual out, under normal circumstances can use the memory includes the next

Then start inserting the element. inserting elements into a list is two lines of code: Next[i]=head;head=i. The first sentence indicates that the next element of the new element I points to the element that the current head points to, and the second sentence is to update the head point, pointing to the new first element I. Once all the elements have been inserted, just start from the be

This topic dragged for several days, because I have two big natural enemies--linked list and tree tut see this topic know the original linked list can not use the pointer to write, but the same principle is the same, the equivalent is to use an array to simulate a list and not practical structure, the pointer in the structure of the body replaced by two variables cur and last. This topic was originally measured to be very strange and good because of the UVA AC HDU TLE Spoj re I was wondering, on
