C language basic expansion (2) and C language basic Expansion
Basic expansion of scanf () functions:
The C function library contains multiple input functions. The most common function is scanf (). It can read input in various formats.
Scanf () can convert the input string into the desired forms, such as integers, floa
method has
Therefore the auxiliary series converges, thus the general term tends to be 0, namely
Therefore,
"Example 2" expands the function at the place into a power series.
Solution:
So he got a power series.
It is easy to find out that its convergent radius is
On the arbitrary, there
As we know from the example,
So, we get an expanded

hash value int i = indexfor (hash, table.length); Return hash (table.length-1) for (entryIt is known from code and annotations that when a collision occurs, the HashMap first obtains the current value E, then e as the next value of the newly created entry, and the newly created entry value as the table, that is, assuming that the hash function is (k%5), There are 21 and 362 numbers, the hash result is 1, then first Entry (21) will be stored in the position of table[1], and when 36 is put into
Uncover new features of SQL Server 2014 (2)-SSD Buffer Pool (buffer Pool) expansion, 2014 Buffer
Introduction
Another good feature in SQL Server 2014 is that SSD can be virtualized into a portion of the memory for the SQL Server data page buffer. By using SSD to expand the Buffer-Pool, a large number of random IOPS can be carried by SSD, thus greatly reducing random IOPS and PAGE-OUT for data pages.

UML Reference Manual
Part 2Basic Concepts
Chapter 4 Expansion Mechanism 11.1 Overview UML provides several extension mechanisms that allow modelers to make some general extensions without changing the basic modeling language. These scaling mechanisms have been designed so that they can be stored and used without understanding all semantics. For this reason, extensions can be stored and
