题目描述:

用一个数组表示股票每天的价格,数组的第i个数表示股票在第i天的价格。交易次数不限,但一次只能交易一支股票,也就是说手上最多只能持有一支股票,求最大收益。

思路:

嗯,与之前不同的是不限交易次数。很基础的贪心,只要当天卖掉的价格减去前一天买入的价格,收益就会增加。

代码:
class Solution {
public:
    int maxProfit(vector<int>& prices) {
        int len=prices.size();
        if(len==0){
            return 0;
        }
        int maxRes=0;
        for(int i=1;i<len;i++){
            if(prices[i]-prices[i-1]>0){
                maxRes+=(prices[i]-prices[i-1]);
            }
        }
        return maxRes;
    }
};

动态时间规整(Dynamic Time Warping,DTW):让时间序列分析不再枯燥和代码全分析

动态时间规整(DTW)是一种用于比较时间序列相似性的算法,特别适用于处理长度不同或时间轴不对齐的序列。本文介绍了DTW的核心概念,包括其通过非线性对齐解决时间扭曲问题的能力,以及在语音识别、金融分析等领域的应用。通过Python代码示例,演示了如何计算两个模拟时间序列的DTW距离,并可视化最优对齐路径。结果显示,DTW能够有效捕捉序列间的相似模式,即使它们在时间轴上存在偏移或伸缩。该算法通过最小化累积距离来评估相似性,得分越低表明序列间相似度越高。
