Where NC is the number of unequal integers in all two sets, NT is the number of unequal integers that have a total of two sets. Your task is to calculate the similarity of any given set.Input format:Enter the first line to give a positive integer n (The line

L2 switching principle:1. receive all data frames in the network segment;2. Use the source MAC address of the received data frame to create a MAC Address Table (Source Address self-learning), and use the update and aging mechanism to maintain the address table;3. search for the destination address in the data frame in the MAC address table. If yes, send the data to the corresponding port (excluding the source port). If no destination address is found,

The number of rescue teams in each city and the length of each fast road connecting two cities are marked on the map. When other cities have an eme

maintains its own address table.The working principle of a L2 Switch can be inferred from the following three points:(1) because the switch exchanges data on most ports at the same time, it requires a wide switching bus bandwidth. If the L2 Switch has N ports, the bandwidth of each port is M, if the bandwidth of the vswitch bus exceeds n × m, the vswitch can achieve line rate switching;(2) the MAC address

Recently in the look at Depth model processing NLP text classification. Generally in the writing model, the L2 regularization coefficient is set to 0, not to run regularization. There is also a small trick, is the initialization of some weights, such as the weight of each layer of CNN, as well as the weight of the full connection layer and so on. In general, these weights may be randomly initialized and conform to a normal distribution. Although the r

Since Layer-3 switches can be considered as composed of routers and common switches, You can first try to install some modules with routing functions during assembly, in this way, there is a layer-3 Switch rich in routing functions. Its functions are equally powerful. Recently, the price of vswitches has been greatly reduced. Some models of some domestic brands have fallen below RMB, which is almost the same as that of hubs. With the updates of People's cognition and the demand for bandwidth, sw

changes the MAC address, you need to change the access list rules. Otherwise, the rules will not work properly. In addition, in some cases, communication between PCs is not allowed, but all PCs are allowed to communicate with a server or gateway. The topology shows: The above functions can be implemented using MAC address-based access control, but the operations are cumbersome. In this case, we can use a private VLAN to implement the above functions: 1. Place the switch interfaces connecting s

Question: New L2 Switch 2918 to L3 switch 3560 Author: Xu minghuiDate: 14: 09 2009/4/20 Steps: 0Connect the 2918 switch to the COM port of the PC and configure the password and IP address.15 ports with 3560 and 1 trunk ports with 2918 taste.2And synchronize VLAN information of 2918 and 3560.3Add a new VLAN on 3560 and assign the VLAN to the port on 2918.4, Supplement knowledge The TXT file of the original configuration file can beHereDownload.

1. Download the lion iatkos L2 dmg, which was originally converted to iso. However, if I thought it was wrong, I didn't use iso. I still directly used DMG to open it with the disk tool under snow leopard, it is burned and burned to a CD.2. Prepare the usb keyboard and mouse (which will be used later)If you want to install Windows 7 and lion, install Windows 7 now. Otherwise, the active partition using the disk tool will drop down the Apple partition.

The switch will send an echo to its neighbor. If the neighbor does not receive a response within a certain period of time, it is deemed that the link with the neighbor has a problem. In normal mode, the link may be regarded as an uncertain state and will not be closed (note that normal mode can only detect misunderstandings of optical fibers, such as Tx and Rx insertion and inversion ). In the aggressive mode, the link is regarded as one-way and closed (the interface is placed in the err-Disable

Finally, the built-up tree BFS can be written hierarchically traversed. The AC code is as follows: #include
