Problem Statement

There are three houses on a number line: House 1, 2 and 3, with coordinates A, B and C, respectively.
Print Yes if we pass the coordinate of House 3 on the straight way from House 1 to House 2 without making a detour, and print No otherwise.

Constraints

0\leq A,B,C\leq 100

A, B and C are distinct integers.

Input

Input is given from Standard Input in the following format:

A B C

Output

Print Yes if we pass the coordinate of House 3 on the straight way from House 1 to House 2 without making a detour, and print No otherwise.

Sample Input 1

3 8 5

Sample Output 1

Yes

We pass the coordinate 5 on the straight way from the house at coordinate 3 to the house at coordinate 8.

Sample Input 2

7 3 1

Sample Output 2

No

Sample Input 3

10 2 4

Sample Output 3

Yes

Sample Input 4

31 41 59

Sample Output 4

No

Solution in Haskell (GHC 7.10.3) (judge verdict: Accepted)

toInt :: (String -> Int)
toInt x = read x ::Int

getInts = do
  x <- getLine
  let y = (map$toInt)$words x
  return y


range x y
  | x > y = [y..x]
  | otherwise = [x..y]
main :: IO ()
main = do
  a_c <- getInts
  if (filter (== (a_c !! 2)) (range (a_c !! 0) (a_c !! 1))) == [] then putStrLn "No"
        else putStrLn "Yes"
