Slicing Slice theory knowledge
It is not an array by itself, it points to the underlying array
As an alternative to programming arrays, you can associate local or all of the underlying array
As a reference type
You can create directly or get a build from the underlying array
Use Len () to get the number of elements, and the cap () to get the capacity
General use make () to create
If multiple slice point to the same und
to modify the array values inside the calling function, you must pass the array pointers, and I have no comment. But the slice part is not that simple. Basically, the following points need to be clarified to explain the above code.The structure of the slice is Uintptr+len+cap
Like I've defined a slice, no matter what the method defines.
var a []int
a = make([]int, 1)
a := []int{1,2}
The A is assigned by a fixed data structure.
This data structure

After the hydrogen raw material is used up, the nuclear reaction of helium and other heavier elements will maintain its energy, turn it into a red star, and then turn it into a red superstar. When all the nuclear energy in the sun is exhausted, it will collapse into a high density white dwarf
Recently in the development of a large project encountered a very headache problem, due to the project code more, each set up a contact 1 minutes. Waste Time debugging. So, some research on how to improve the speed of compiling links here for everyone to share.To improve the speed of compiling and linking in the following three ways:1. Increase the number of threads used by Xcode compilationDefaults Write Com.apple.Xcode pbxnumberofparallelbuildsubtasks 4Xcode is compiled by default using the sa

There are three main ways to increase the speed of compiling links:
1. Increase the number of threads used when Xcode compiles
Copy the code code as follows:Defaults Write Com.apple.Xcode pbxnumberofparallelbuildsubtasks 4
Xcode is compiled by default using the same threads as the CPU cores, but because the IO operations in the compilation process tend to be more than the CPU, the appropriate number of lifting threads can speed up the compilation to some extent. I am using a 4-core CPU, t
correctly point out of the object, including front cap and back cap.5. the above is a simple process, the shadow is very hard, you can slightly change it: first render it with ambient light, then calculate the template, then use the template to render the scene, and finally deepen the shadow with Alpha blend.
Next we will start to map a large area. First, let's take a look at the specific example of Z-fai

follows:The first flow is 4-->3, the flow is 20 and the cost is 3*20=60.The second stream is 4-->2-->3, the flow is 20, and the cost is (2+1) *20=60.The third stream is 4-->2-->1-->3, the flow is 10 and the cost is (2+9+5) *10=160.So the maximum flow is 50, in this case the minimum cost is 60+60+160=280.So output 50 280.90 Points of MCMF (Dijkstra is stuck constant)#include #include#include#definePir pair#defineINF 0x33333333using namespacestd;Const intn=1e4+Ten;Const intm=1e5+Ten;structnode{in

. \ (R (B _1) \) indicates the number of records corresponding to the condition \ (B _1 \). It can be calculated using the records_in_range function;
\ (P (X | Y) \) indicates the conditional probability when the Y condition occurs. Here we assume that all conditions are evenly distributed, and the degree of selection is probability. P (X | Y) = P (X) * P (Y | X );
Then, after the set \ (B _1 \) is merged to set A, the degree of selection is calculated:
