interviewbit time complexity solutions

Otherwise, if I try to "go back one step" on the FIRST element that I initially modified, it means that there were no solutions. The problem will now turn to find out local maximum and local minimum, under the condition that local maximum should fall after the local minimum. Email * Password * Remember Me Here we are allowed to make only one transaction (exactly one buy and one sell). Similarly, we can observe that if all are stock prices are in strictly decreasing order the maximum profit for transaction can occur if and only if you buy the stock on one day and sell it the same day and this maximum profit value = 0.
