主成分分析(PCA)是多元统计分析中用来分析数据的一种方法,它是用一种较少数量的特征对样本进行描述以达到降低特征空间维数的方法,(Principal Component Analysis (PCA) is a method used to analyze data in multivariate statistical analysis. It uses a small number of features to describe samples in order to reduce the dimension of feature space.)

字符串交叉输入，就是将一个字符串交叉的输入到了另一个字符串当中，比如： char a[4]="ABCD" char b[4]="abcd" 则char c[8]="AaBbCcDd" (Cross-string input, is to cross a string input to another string of them, such as: char a [4] = "ABCD" char b [4] = "abcd" While char c [8] = "AaBbCcDd" )

分治法思想，求最邻近点对，考虑将所给的n个点的集合S分成2个子集S1和S2，每个子集中约有n/2个点，然后在每个子集中递归地求其最接近的点对(Divide and conquer ideas, find the nearest point to consider given the set S of n points into two subsets S1 and S2, each subset of about n/2 points, and then recursively find its focus in each sub-the closest point)
