LeetCode122买卖股票的最佳时机 II-C语言、Python

A+B+C 的和等于差值 D 所对应的连续峰和谷的高度之差。

C语言版：

int maxProfit(int* prices, int pricesSize) {
    int i;
    int profit = 0;
    for(i = 0; i < pricesSize - 1; i++){
        if(prices[i] < prices[i + 1])
            profit += prices[i + 1] - prices[i];
    }
    return profit;
}

Python版：

class Solution:
    def maxProfit(self, prices):
        """
        :type prices: List[int]
        :rtype: int
        """
        profit = 0
        for i in range(len(prices) - 1):
            profit += max(prices[i + 1] - prices[i], 0)
        return profit
