Examples

Example 1
INPUT
prices = [3,3,5,0,0,3,1,4]
OUTPUT
6
EXPLANATION

Buy on day 4 (price = 0) and sell on day 6 (price = 3), profit = 3-0 = 3. Then buy on day 7 (price = 1) and sell on day 8 (price = 4), profit = 4-1 = 3.

Example 2
INPUT
prices = [1,2,3,4,5]
OUTPUT
4
EXPLANATION

Buy on day 1 (price = 1) and sell on day 5 (price = 5), profit = 5-1 = 4. Note that you cannot buy on day 1, buy on day 2 and sell them later, as you are engaging multiple transactions at the same time. You must sell before buying again.

Example 3
INPUT
prices = [7,6,4,3,1]
OUTPUT
0
EXPLANATION

In this case, no transaction is done, i.e. max profit = 0.

Constraints

1 <= prices.length <= 105
0 <= prices[i] <= 105
