Buy and sell Stock to get Max profit
Whether you're a seasoned trader or a beginner, understanding the art of stock trading can lead to substantial financial gains. This is important that will gain profit in stock trading. The program we will solve here from an integer array of stock price at what point we sell our share to gain maximum profit.
In this exercise we have given the array of integer values. form this array we have to find at what point we need to exit form the stock to gain the maximum profit.
def max_profit(prices): if len(prices) < 2: return 0
min_price = prices[0] max_profit = 0
for i in range(1, len(prices)): if prices[i] < min_price: min_price = prices[i] else: profit = prices[i] - min_price if profit > max_profit: max_profit = profit
return max_profitprices = [7, 1, 5, 3, 6, 4]profit = max_profit(prices)print(profit)# Output: 5
In this example, the prices list is [7, 1, 5, 3, 6, 4], and the max_profit function is called to calculate the maximum profit from buying and selling stocks based on these prices.
