: 0 or 0 = 0, 1, or 0 = 1, 0, or 1 = 1, 1 = 0 (0, 1). These rules are the same as addition, only do not bring in bits. There are three kinds of calculus in the XOR, EOR, and ex-or programs: XOR, XOR, and ^. The usage is as follows: z = x ^ y; Z = x XOR y;
Algorithm:
1. A ^ A = 02. A ^ B = B ^ A3. a ^ B ^ c = a ^ (B ^ c) = (a ^ B) ^ C; 4. D = a ^ B ^ C can introduce a = d ^ B ^ C.5. a ^ B ^ A = B .6. if X is a binary number of 0101, if y is a binary number of 1011, then x ^ y = 1110 only returns
sum of the bandwidth difference". Below we use the "difference" as a column to briefly prove that, lx indicates the lower bound of range X, UX indicates the upper bound of range X, and wx indicates twice the width of range X (the reason is to double the width of range X for the convenience of writing the following proof, every expression divided by 2 is too tedious to write ):(Width (sub-interval x y ))=> (W (make-interval (-
Tcpdump can help us capture and save network packets, save the network packets can be used to analyze the network load, packets can be resolved by the tcpdump command, can also be saved as a suffix pcap files, using Wireshark and other software to view.
Here are 9 examples of using tcpdump to illustrate the specific use of tcpdump.
1. For the specific mesh grab bag (-i option)
When we execute tcpdump without any options, the tcpdump will crawl through the first port of the packet, using the-i

The IEEE 802.3z Gigabit Ethernet Standard, adopted in June 1998, describes 3 physical layer interfaces (1000BASE-SX, 1000BASE-LX, and 1000BASE-CX) that are used for a universal link encoding and can be 1000mb/s transmitted. 1000BASE-SX, 1000BASE-LX interface using optical fiber as a medium, the farthest transmission distance of up to 5000 meters, so can be used in buildings or campus backbo

The Chinese meaning of Mutalbe is "changeable, variable" and is the antonym of constant (const in C + +).
In C + +, mutable is also set to break the const limit. Variables modified by mutable will always be in a mutable state, even in a const function.
We know that if the member function of a class does not change the state of the object, then the member function is generally declared as Const. However, sometimes we need to modify some data members that are not related to the class state in th

Successfully completed 3 even t! Yes, three-way tle is simply not good enough, so roll to see if the template is a problem. Took 3 copies of the other P-party template and threw it up, eh continue tle ... Konjac Konjac said he was powerless ...Thought like paper inside said, still two minutes length then group ... Then record the maximum and minimum values of each character to determine if the entire set is satisfied ... Done... It's actually quite simple to write ...Constmaxn=100419;varH,sum,ra
Online a bunch of people to write km algorithm, have not found out which speak better.KM algorithm approximate process:(1) Initializes an LX array to the one of the boy's most weighted edges. Initialize the LY array to 0.(2) For each boy, find a Girl object with DFS, record the S and T sets on the way, and update the slack value for each girl. If the object cannot be found, go to 3.(3) Finding the minimum slack value of girl for non-T sets is D, updat
The maximum weighted bipartite match problem is to give each edge of the Bipartite Graph A weight value, and select several non-intersecting edges to obtain the maximum total weight. To solve this problem, you can use the KM algorithm. To understand the KM algorithm, you must first understand the concept of "feasible top mark. A feasible top mark refers to a value of LX [I] Or ly [J] for each vertex on both sides of a bipartite graph. ensure that
