Collar button LintCode algorithm question answer - 856 Sentence similarity
856. Sentence similarity
Given two sentences words1 and words2 (each represented by a string array) and a similar word pair array pairs, you need to judge whether the two sentences are similar.
For example, if similar word pairs are pairs = [["great", ...

Object search, detection and recognition using OpenCV
In this tutorial, we will understand the important concept called "selective search" in object detection. We will also share OpenCV code with C + + and Python.
Object detection and object recognition
The object recognition algorithm recognizes which objects exist in the image. It takes the whole image as the input and outputs the cl ...

Concept of string
String: a finite sequence of zero or more characters, also known as a string
Some strings
Empty string( null string)，It is zero in length and can be directly represented by two pairs of quotation marks ""
The so-called sequence shows that the adjacent characters of the string have the relationship between ...

Linked storage structure -- implementation of one-way linked list (Java)
Data structure - one way linked list
preface
In the previous chapter, we implemented the linear table using the sequential storage structure. We found that the query efficiency of the linear table is very fast and the time complexity is O(1), but the efficiency of adding and deleting data is relatively low. Based on these problems, th ...

Minimum spanning tree and shortest path algorithm for weighted graph - java implementation
Weighted Graph Correlation Algorithm
foreword
This paper mainly introduces two important applications of weighted graph algorithm: minimum spanning tree and shortest path.
The weighted undirected graph is used to find the minimum spanning tree, and the minimum spanning tree algorithm of the weighted directed graph becomes the "minimum genu ...
