The buy must occur before the sell (meaning no short sell is allowed). So, for example, the inputs are 1, 2 and 4. It also implies that your solution to the stock selling problem is also incorrect (a counter example can be constructed in a similar manner). The reason is let's say if you buy on day 6, then from day 5 to day 6, there will be no profit, or else the findMaxProfit() would have included day 5. And you buy at price 2, the third day you sell at price 4 so you have another profit 2. If they are instead , no profit can be made so you don't buy or sell stock those days. You signed in with another tab or window. You can complete up to two transactions. (day in the description is also 0 index based). The simple answer is no; not that it will dissuade you any, LOL.

Two subarray [0, 1) and [2, 5) add up to 12, yielding an optimal solution. The brute-force algorithm we settled on above, using our python implementation, won't work: In the maximum subarray problem (Chapter 4), the author claims that the maximum profit of buying and selling a share cannot be calculated just by finding the maximum and minimum of the array. So you need to find a pair (buyDay,sellDay) where buyDay < = sellDay and it should maximize the profit. www.algoexpert.io Ace the Programming Interviews with 65 video explanations of popular interview questions.
