该程序实现了KNN搜索算法，可以实现输入不同的维数和样本点个数来进行搜索。-The program implements the KNN search algorithm, can enter a different dimension and the number of sample points to be searched.

机器学习K近邻分类算法，使用的是C++编程。如果一个样本在特征空间中的k个最相似(即特征空间中最邻近)的样本中的大多数属于某一个类别，则该样本也属于这个类别。-K-nearest neighbor classification machine learning algorithm, using the C++ programming. If a sample in feature space is k most similar (i.e., the feature space adjacent
