|
|
|
## Goal
|
|
Given is the price-development of an arbitrary stock.
|
|
|
|
|
|
|
|
Suppose you have perfect knowledge and are able to buy and sell the stock once.
|
|
Write an algorithm that outputs the maximum profit that can be made.
|
|
|
|
* The price-development is given for an arbitrary number of days.
|
|
* A stock can only be sold on the next day.
|
|
* Stock-prices are given as integers
|
|
|
|
### Input
|
|
A blank-separated array of stock-prices.
|
|
|
|
Each position symbolises the stock-price of a given day.
|
|
|
|
### Output
|
|
The maximum profit that can be made within that day.
|
|
|
|
### Constraints
|
|
* 2 <= `days with stock-prices` <= 50
|
|
* 1 <= `stock-price` <= 2,147,483,647
|
|
|
|
### Example
|
|
**Input:**
|
|
`310 315 275 295 260 270 290 230 255 250`
|
|
|
|
**Output:**
|
|
`30` |
