, or K nearest neighbor (Knn,k-nearestneighbor) classification algorithm, is one of the simplest methods in data mining classification technology. The so-called K nearest neighbor is the meaning of K's closest neighbour, saying that each sample can be represented by its nearest K-neighbor.The core idea of the KNN algorithm is that if the majority of the k nearest samples in a feature space belong to a category, the sample also falls into this category and has the characteristics of the sample on

Brief Description:Guessing number problem: There is an integer in the range of 1 to n that is guessed x, you can give an integer y each time. You will get the answer to your question after you ask the next question, that is, the size of x and Y. And if you get a K-xAnalyse:F[I][J], which represents the number of times I guess, the processing length of the condition of the J-XFriend Chain: The research paper
