Best time to buy and sell stock

#1

i want to know how can i print the value of buy and sell whenever buy and sell is updated… help me

#2

for (int i = 0; i < v.size(); i++)

{

    for (int j = i+1; j < v.size(); j++)

    {

        int profit  = v[j] - v[i];

        if (profit > maxProfit)

        {

            maxProfit = profit;

        }

    }

}

In your code snippet above, you can see that if profit is getting larger than maxprofit, than means we have found a new buy/sell pair. So inside the if condition you can print buy as v[i] and sell as v[j]
