Title: Enter two fractional rational numbers in the form of A1 / B1 and A2 / B2 in one line, where the numerator and denominator are all integers within the integer range, the negative sign can only appear in front of the numerator, and the denominator is not 0. Output format: Output the sum, difference, product and quotient of two rational ...

KNN(K-Nearest Neighbors) generally refers to K-nearest neighbor algorithm, which is a common classification algorithm in machine learning The purpose of this paper is to quickly teach you an intuitive understanding of KNN algorithm. At the same time, in order to facilitate you to implement the algorithm, the model involved in this paper is deve ...

I wrote a related article two years ago: Sorting algorithm - merge sorting The reason why we have another article today is that we have a deeper understanding of this algorithm. Algorithm analysis Here, we will paste the dynamic diagram of merge sorting algorithm again: [external chain picture transfer failed. The source station may have anti ...

Recently, I reviewed the sorting algorithm. Although I have studied it before, I forget it almost if I write it directly, even if I have written relevant before article , let's summarize the idea of quick sorting here. First, post the animation demonstration of quick row here: partition If you want to remember the implementation of fast ...
