# Intuition\n<!-- Describe your first thoughts on how to solve this problem. -->\nThe given code is a solution to the problem of finding the maximum profit that can be obtained from buying and selling stocks. The class Solution contains a single member function maxProfit that takes a vector of integers prices as input and returns an integer value representing the maximum profit.\n\n<!-- Describe your approach to solving the problem. -->\n # Explain with Matplotlib.pyplot\n[Please turn on English subtitles]\n[https://youtu.be/--vVXnaKPqI](https://youtu.be/--vVXnaKPqI)\n# Approach\nThe following loop iterates through the prices vector starting from index 1 (since we already initialized buy with the price at index 0):\n\nbuy = min(buy, prices[i]);: \nThis line compares the current price (prices[i]) with the current minimum price (buy). It updates buy if the current price is smaller, ensuring that buy always represents the minimum price seen so far.\n\nsell = max(sell, prices[i] - buy);: \nThis line calculates the profit that can be obtained by selling at the current price (prices[i]) after buying at the minimum price (buy). It compares this profit with the current maximum profit (sell) and updates sell if the calculated profit is larger. This way, sell always represents the maximum profit seen so far.\n\n# Complexity\n- Time complexity:\n<!-- Add your time complexity here, e.g. $$O(n)$$ -->\n$$O(n)$$\n- Space complexity:\n<!-- Add your space complexity here, e.g. $$O(n)$$ -->\n$$O(1)$$\n# Code\n```\nclass Solution {\npublic:\n    int maxProfit(vector<int>& prices) {\n        int&& s=prices.size();\n        if (s <= 1) return 0;\n        int buy = prices[0], sell=0;\n        for (int i = 1; i < s; i++) {\n            buy = min(buy, prices[i]);\n            sell = max(sell, prices[i] - buy);\n //           cout<<buy<<"|"<<sell<<endl;          \n        }\n        return sell;\n    }\n};  \n  \n```\n# Python Code\n\n```\nclass Solution:\n    def maxProfit(self, prices: List[int]) -> int:\n        #List & Loop \n        profit=0\n        buy=prices[0]\n        for x in prices[1:]:\n            buy=min(buy, x)\n            profit=max(profit, x-buy)\n        return profit\n```
