Written in front Thinking analysis Understanding the meaning Given a list and K, after traversing the list, the nodes < 0 will be output first, then the nodes in the range of 0-k will be output, and finally the nodes in the range of > k will be output. Specific realization: 1. All nodes ar ...

GetInterMerge Candidates () function is a very important function in inter-frame prediction technology. It is the constructor of Merge list. All Merge modes must first construct a Merge candidate list, and then extend the corresponding Merge list on the basis of this regular Merge list according to diff ...

Title: Give a tree with $n $dots, $m $queries. Give $x $for each query, and find the smallest $k $to break the $k $edge off the tree and reconnect the $k $edge to form a new tree. The tree's center of gravity is $x$. $ $ The center of gravity of a tree: For every node in a rootless tree, the node with the largest subtree and the smallest subtre ...

The idea of quick sorting is dichotomy. Ideally, every dichotomy can divide the data sequence equally, so the recursive hierarchy is logN. The worst case is that every dichotomy is divided into 0 and n, which will be infinitely recursive, and eventually stack overflow. Or each time is divided into 1 and n-1, which will recurse n times. If n is ...

In the process of interface testing, most data interaction uses json format, but the effect of json output from console is far less beautiful than that of browser plug-in. After searching for some information, I decided to write a formatting method to output json information to the console. After some attempts, it has been completed. Share as f ...

The first is that the double for cycle makes the calculation of divisors and dividends extremely inefficient. public void test1(int n){ long start = System.currentTimeMillis(); //Take the start time int num=0; boolean sign; for(int i=2;i<n;i++){ if(i % 2 == 0 && i != 2 ) conti ...

Algorithmic idea: splitting an unordered sequence into a subsequence with only one keyword, and then merging two sequences until merging into one sequence Time complexity analysis: a total of log2n sorting operations are needed, each sorting performs n merging operations, so the time complexity is ...

I. Application scenarios Shopping malls adopt different discount strategies for different customers. Different construction methods are used for different topography and landforms, and different algorithms are selected for different batch data processing. For commonly used     if() {     }else ...
