Score : 100 points

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

Solution in Python (3.4.3) (judge verdict: Wrong Answer)

from sys import stdin


def answer(B, C):
    if B > C:
        print("Yes")
    else:
        print("No")


def main():
    A, B, C = [int(x) for x in stdin.readline().split()]
    if A < B:
        answer(B, C)
    else:
        answer(C, B)


if __name__ == "__main__":
    main()
