Algorithm competition entry classic 6.3.1 Binary Tree-ball fall, java Ball fall
There is a binary tree with the maximum depth of D and the depth of all leaves is the same. Numbers of all nodes from top to bottom from left to right are 1, 2, 3 ,..., 2eD-1. Place a ball at Node 1 and it will fall. Each node has a switch, which is initially closed. When a ball falls

Summary of several situations of vector vectors in c ++ (vector pointer and pointer vector)
1. Standard Library vector type
Vector is a set of objects of the same type. Each object has a corresponding integer index value. The standard library will be responsible for managing
Vectors are vector types that can hold many types of data, such as several integers, so they are called containers. Vector is an important member of the C + + STL, and you need to include the header file when you use it:
Copy Code code as follows:
#include
Vector initialization: There are five ways to do this, examples are as follows:
(1)
In practice, the vector series in c ++ -- vector (unique_ptr () is assigned to vector (unique_ptr ())
Previously, we mentioned that the insert method can be used to copy a vector to the end of another vector.
As mentioned in previous blogs, if unique_ptr is placed inside the
In practice, the vector series in c ++ -- vector traversal (stl algorithm, vector iterator (do not judge not equal to end () in the loop), operator [])
There are many ways to traverse a vector container.
Index traversal:
for (i = 0; i
Iterator traversal:
for (vInt::const_iterator iter = v.begin(); iter != v.end();it
Previous blogs about vectors you can use the Insert method to copy a vector to the back of another vector.Previous blogs have also talked about the need to transfer ownership if the vector container is placed inside the unique_ptr.Come on, now. 818 HowvectorIf you have a regular vector, we can use insert like this://inserting into a
Vector series in practice c ++-sort the vector using the sort algorithm (sort the vector (string) and use stable sorting std: stable_sort ())
After writing a lot of vector operations, we encountered the Sorting Problem of the vector in our work. Here we will discuss it.
Use
In three-dimensional space, the product of two vectors (a vector product, an outer product, a product, a multiplication of multiples of two vectors: the inner product, the dot product) represents the torque of two vectors, and the mixed product axb of three vectors C, the area of the parallelepiped that is composed of three vector a,b,c. And the position of a,b,c in the mixed product is interchangeable (thi
In practice, the vector series in c ++ -- creating vector of local structure AND vector of structs initialization
I have never used it beforeVector
Now, write a short code:
#include

int main() { struct st { int a; }; std::vector

I've never used it before.vector#include #include intMain () {structSt {intA };STD:: vectorV V.resize (4); for(STD:: vector:: Size_type i =0; I operator[] (i). A = i +1;//v[i].a = i+1;} for(inti =0; I STD::coutSTD:: Endl; }}Compile successfully with VS2015, run result:1234However, this is only allowed after c++11, the compiler does not allow you to write such a syntax, the vector container is not allowed to
C ++ copies the content in a vector to the end of another vector and ends with the vector.
When using the vector container, We need to copy the content of a vector to the end of another vector. How can this problem be achieved?
See C++primer Plus look bored, the first time do Leetcode practice, originally want to do two-dimensional vector, results always pass, check the reason, must use one-dimensional ...One-dimensional answers:Class Solution {PublicVector{int cout = Nums.size (); Get the size of the vectorvectorfor (int i = 0; i{for (int j = i + 1; j{if ((Nums[i] + nums[j]) = = target){Ret.push_back (i); Get the location of the target valueRet.push_back (j);}}}return ret;}
We fell for recurrent neural networks (RNN), Long-short term-memory (LSTM), and all their variants. Now it's time to drop them!
IT is the year 2014 and Lstm and RNN make a great come-back from the dead. We all read Colah's blog and Karpathy ' s ode to RNN. But We were all young and unexperienced. For a few years this is the way to solve sequence learning, sequence translation (SEQ2SEQ), which also resulted in Amazin G results in speech to text comprehension and the raise of Siri, Cortana, Google
The IEEE Signal processing Magazine issued in March contains a paper "Radar Signal processing for elderly Fall Detection". This was probably the first survey paper of using radar techniques for human activity surveillance. The motivation of using radar for fall detection are that, the electromagnetic wave would have the so called Doppler effect Under Motions. Through capturing the Doppler effect signature s
