Input

The input is a single line containing space seperated integers.

Output

Explanation

In the example the given prices are 7 1 5 3 6 4.

buying stocks on day two having price 1 and selling them on the fifth day having price 6 would give the maximum profit which is 6 - 1

Answer 1

def profit(prices):
	maxProfit = 0
	if len(prices) > 2:
		for i in range(len(prices)-1):
			for j in range(i+1, len(prices)):
				if prices[j] - prices[i] > maxProfit:
					maxProfit = prices[j] - prices[i]
	return maxProfit


prices = [int(i) for i in input().split()]
print(profit(prices))
