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

int main()
{
  int cnt;

  int i;

  cnt = scanf("%d %d %d", &a, &b, &c);

  if (a < b) {
    if ((a <= c) &&
        (c <= b)) {
      printf("Yes");
      return 0;
    } else {
      printf("No");
      return 0;
    }
  }

  if ((b <= c) &&
      (c <= a)) {
    printf("Yes");
    return 0;
