Test data for network flow 10, test data for network flow

One. Algorithmic analysis of binary linked lists established with precedent inputs:

CreateBinTree(Bintree *bt) uses the binary linked list as the storage structure to create a binary tree bt, and bt is a pointer to the root node of the binary tree.

In the process of algorithm implementation, firstly, it is determined whether the value of the node is 0, if it is 0, it is returned, and the input ends here. When the input is not 0, its value is the value of the node, and then the left and right nodes are entered respectively, and the input principle is as above.

Two. Algorithmic analysis of root traversal:

According to the recursive definition of the binary tree traversed in order, a stack is used to save the returned nodes when converting to a non-recursive function, first scanning the root node to merge into the stack, leaving the stack one node, accessing it, then scanning the left node of the node to merge into the stack, and then scanning all the right nodes of the node to merge into the stack, and so on until the stack is empty.

Three. Analysis of the middle-order traversal algorithm:

According to the recursive definition of the mid-order traversal binary tree, a stack is used to save the returned nodes when converting to a non-recursive function, first scanning all the left nodes of the root node to merge into the stack, leaving one node out of the stack, accessing it, and then scanning the right nodes of the node to merge into the stack, and then scanning all the left nodes of the right node to merge into the stack, and so on until the stack is empty.

Four. Algorithmic analysis of hierarchical traversal:

This algorithm uses a queue q, first put the root node of the binary tree into the queue, and then dequeue it, output the node, if it has a left subtree, the root node of the left subtree will be queued, if it has a right subtree, the root node of the right subtree will be queued, and so on until the queue is empty. Because the queue is characterized by first-in, first-out, so as to achieve the purpose of traversing the binary tree in hierarchical order.

Five. Finding the Depth Algorithm of a Binary Tree:

If a binary tree is empty, its depth is 0, otherwise its depth is equal to the maximum depth of the left and right subtrees plus 1Recursive model:

depth(b)=0 if b=null

For example: depth(b)=max(depth(b->left,b->right)+1 other.

poj1273 Look at the discussion, someone left the data.

Go to the Internet to search for 24 questions, there are questions, solutions, and test data.

The original tree chain is split and the line segment tree is built.

For each traveling businessman from the origin to the traveling merchant CI, the traveling merchant to the segment tree corresponds to the interval infinity.

The city connects to the meeting point

The maximum stream is sufficient.

Analyze with packet capture software.

Wireshark is available in Chinese.

Once the user has decompressed the data through the decompression device, the program will be displayed as it was before it was sent.

The difference can be seen from the definition of the data flow of the stream** is compressed.

The course teaches the design and analysis skills of efficient algorithms, with an emphasis on methods of practical value. Topics include: sorting, stacking, and hashing; Breaking methods, dynamic programming, network flow, computational geometry, numerical theoretical algorithms, caching technology and parallel operations, etc.

It is a new algorithm for network traffic anomaly detection. The algorithm combines the linear model with the wavelet transform to solve the problem that the threshold monitoring cannot be alarmed and monitored. In the actual network data SNMP MIB and NetFlow application detection, the performance is good.

Compared with the GLR algorithm, the judgment of outliers is more timely, accurate and reliable.

The traffic generated by the macro operation of the Internet in China can be monitored by analyzing information such as protocols, addresses, ports, packet lengths, traffic, and time series. Why should the above be so verbose and hope to adopt.

The return value of the receive is the number of bytes received, and when it is 0, it indicates the end of the transfer, otherwise it is received in a loop.

The buffer doesn't need to be too big, 8k or 64k depending on the situation.

byte recvbytes = new byte[1024*8];

int ibytes = 1;

string strallhtml = "";

while (ibytes > 0)

You set a flag on the sender to indicate that what I sent has been sent, and when you accept it, determine whether there is this flag in the accepted network flow, and if so, it means that it has been received. Otherwise not.

How can you tell if you're done with the data you've received? Assuming your buffer recvbytes size is smaller than your data, what do you do with the rest of the data?

So there are actually 2 problems here.

1. The data is less than or equal to the buffer: then recvbytes should be the complete content you received;

2. The data is larger than the buffer: then it is necessary to receive it multiple times, here it is necessary to determine the size of the data you need to receive, and when the received data is less than the data that needs to be received, execute it many times until recvtotal==defaulttotal.
