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

   #include <stdio.h>
   #include <stdlib.h>
   int main(int argc, char **argv) {
       size_t r;
       int a, b, c;
   
       r = scanf("%d %d %d", &a, &b, &c);
       (void)r;
   
       if (a > b) {
           int t = a;
           a = b;
           b = t;
       }
       if (a < c && c< b) {
           printf("Yes");
       } else {
           printf("No");
       }
       return 0;
   }
