Question: Let us suppose we had an array whose ith element gives the price of a share on the day I.If you were only permitted to buy one share of the stock and sell one share of the stock, design a algorithm to find the Best times to buy and sell. Ask for the best time to buy and sell, which is the point of maximizing profits. A profit is generated when the stock price is less than the stock price at the time of the sale.At first glance, we might think of finding the minimum and maximum po

matrix)First introduce several concepts:1. TP: Zhenyang. is actually true for true predictions.2. FN: false Yang. is to actually be false for true predictions.3. FP: false Yin. is to actually be true for false predictions.4. TN: True Yin. is the actual false prediction.The detailed table (matrix format) that lists these parameters is the confusion matrix, as shown in:　　This kind of form can help people to evaluate the quality of classification very well.
