Say you have an array, A, for which the ith element is the price of a given stock on day i.
Design an algorithm to find the maximum profit. You may complete at most 2 transactions.
Return the maximum possible profit.
Note: You may not engage in multiple transactions at the same time (ie, you must sell the stock before you buy again).
The first and the only argument is an integer array, A.
Return an integer, representing the maximum possible profit.
1 <= length(A) <= 7e5 1 <= A[i] <= 1e7
Input 1: A = [1, 2, 1, 2] Output 1: 2 Explanation 1: Day 0 : Buy Day 1 : Sell Day 2 : Buy Day 3 : Sell Input 2: A = [7, 2, 4, 8, 7] Output 2: 6 Explanation 2: Day 1 : Buy Day 3 : Sell
NOTE: You only need to implement the given function. Do not read input, instead use the arguments to the function. Do not print the output, instead return values as specified. Still have a question? Checkout Sample Codes for more details.
