看別人[解答](https://leetcode.com/problems/best-time-to-buy-and-sell-stock/solutions/3914105/most-optimized-solution-easy-to-understand-c-java-python)才會

class Solution {
public:
    int maxProfit(vector<int>& prices) {
        int min_price = prices[0];
        int maxprof = 0;

        for(int i=1;i<prices.size();i++){
            maxprof = max(maxprof,prices[i]-min_price);
            min_price = min(prices[i],min_price);
        }

        return maxprof;
    }
};

這次學會兩個新的STD

2. min(): [min()教學](https://shengyu7697.github.io/std-min/)
