Function dialog box, first select math and trigonometric functions in the "Function category" column of the dialog box, and then select "Sum" in "Function name" and press "OK" to exit.
(2) Select the range of cells you want to calculate. When the function is selected, the function parameter Input dialog box opens. Then click the Collapse Dialog button (that is, the button to the right of the Number1), the dialog disappears, then select the range of cells, select the method (click C4 Drag to

Step 4: In order to be able to enter the selected content into the C3 and C4 cells, you need to set the appropriate formula and match the cell font color settings to the background color.

. Assuming that the initial state is that all vertices in the graph have not been accessed, the depth-first traversal can proceed from a vertex v of the graph, access this vertex and then proceed from the unreachable adjacency Point of V to the depth first to traverse the graph until all the vertices in the diagram and V have paths are accessed; The above procedure is repeated until all vertices in the diagram are accessed, as an inaccessible vertex in the other diagram.
The process of depth-fir
Minimum spanning tree
Selecting the n-1 edge in a connected graph with n vertices, constituting a minimum connected subgraph, and minimizing the sum of the weights on the n-1 edge of the connected subgraph, it is called the minimum spanning tree of the connected network.
For example, a connected network, as shown in the above figure G4, can have multiple spanning trees with different weights combined.

Selecting the n-1 edge in a connected graph with n vertices, constituting a minimal connected sub-graph, and minimizing the sum of the weights of the n-1 bars in the connected sub-graph, it is called the smallest spanning tree of the connected net.For example, for a connected network as shown in Figure G4 above, you can have multiple spanning trees with different weights.

Article Title: Wonderful sys requests. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
This technique is useful if you are using a development kernel or device driver or running code that can cause serious Kernel errors on your machine.
This technique is applicable to x86, PowerPC, or iSCSI processors in Lin

OBFUSCATOR-LLVM (OLLVM) is a code obfuscation tool developed by the Northwestern University of Applied Sciences Security Laboratory for LLVM compiled components, which is fully open source to increase the difficulty of reverse engineering and ensure the security of the code. OBFUSCATOR-LLVM (OLLVM) integrates compilers and is compatible with all languages supported by LLVM (c,c++, Objective-c, Ada and Fortran) and platforms (x86, x86-64, PowerPC,

Portability
Windows is designed to run on multiple hardware platforms. The original version of Windows NT supports the x86 and MIPS architectures. For the Alpha AXP platform of Dec (acquired by Compaq and then merged with HP), although it is a 64-bit processor, Windows NT runs in 32-Bit mode, Windows has also tried to support it. During Windows 2000 development, a native 64-bit version was not released. In the fourth-generation processor architecture, Motorola
, because so many code uses "int" as the index variable.
It is worth noting that the unsigned overflow is guaranteed to be a 2's complement overflow (bypass), so you can always use them. The price that causes signed integer overflow is defined by the loss of these types of optimization (for example, a common symptom is that there are a large number of signed extensions in a loop on a 64-bit platform ). Both clang and GCC accept the "-fwrapv" mark, which forces the compiler to define signed integ
