Problem DescriptionTo solve the problem of graph theory, we should first think about the way to store the graph. But Xiao Xin but how also do not understand how to save a map to help solve the problem. Can you help him solve the problem?
InputMultiple sets of inputs to
Induction:LinearContinuous storage of "arrays"Advantage: Fast access (element can be directly located)Cons: Insertion of deleted elements is slow (because you want to move other elements), space is usually limitedDiscrete storage "linked list"Advantage: No space limit, insert delete element quicklyCons: Access speed is slow (to one traversal, one for one)Application of linear structure:1. Stack2. QueuesNonl
The storage structure of the graph holds two types of information:1) Vertex data2) The relationship between vertices
Sequential storage: Any two vertices may be associated, and the relationship between elements cannot be represented by the physical location of the element in the store.Multi-linked list: Similar to a tree, wasting storage units
Json_encode and serialize can make the array into a string into the database, two which is more convenient and efficient?

It is recommended to use json standard format storage, which is not only convenient for making
In general, small companies have lower overall storage requirements and fewer users, so the capacity and performance requirements are less stringent. and medium-sized storage companies pay more attention to whether the price is reasonable, the use is convenient. The midrange disk array has a limited number of disks, and prices are much cheaper than those of large
definition of a linear table: A finite sequence of n data elementsLinear tables are categorized from storage structures: sequential storage structures (arrays) and chained storage structures (linked lists)Sequential storage structure: a contiguous memory space is used to store the data in the table l= (a1,a2,a3....an)C

A storage device is directly connected to a computer through a SCSI interface or fiber channel. Das products include storage devices and integrated simple servers, which can be used to implement all functions related to file access and management.

How to spend a limited amount of money on a more cost-effective storage product is the most vexing problem for the small and medium-sized enterprises that are currently growing in storage demand. In the storage disk array, with the upcoming launch of the 6Gbps SAS standard, in the
To better support big data applications, Fujitsu has launched an all-flash array and big data all-in-one machine optimized for big data. This ensures the high performance and high reliability of the entire system, this further improves the efficiency of data processing and analysis. Big Data is another important change that will change traditional business models and IT application methods after cloud computing. From the
Multi-dimensional static and dynamic array storage and access
I. first look at the following section of code for allocating multidimensional static arrays.
# Include
Using namespace STD;
Int main (INT argc, char * argv [])
{
Char sz_temp [3] [3]; // allocate a static two-dimensional array
Char (* sz) [3] = NULL; // pointer Initialization
SZ = (char (*) [3]) sz

each write operation requires access to the parity disk, where the parity disk becomes the bottleneck of the write operation, so RAID 4 is rarely used in a commercial environment.RAID5parity (XOR) stripestorage, calibration data distributed storage, data stripe storage unit is block. RAID 5 does not specify a single parity disk, but instead accesses data and parity information across all disks. On RAID 5,

First look at the following code
#include
int main (void){
int a[5] = {1, 2, 3, 4, 5};int *ptr1 = (int*) (a + 1);int *ptr2 = (int*) ((int) a + 1);
printf ("%x%x\n", Ptr1[-1], *ptr2);
return 0;}
interested friends can guess what the output value will be =.=~
give the answer "5 2000000"
This involves a problem with the meaning of the C array name and the size-end
1. Sequential Storage structure:
The sequential storage structure of binary tree is to store nodes in binary tree with one-dimensional array.
2. Complete two-fork tree:
Because of its structural characteristics, the complete binary tree is usually stored in sequential storage mode. A linear series of nodes is obtain
