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 C (GCC 5.4.1) (judge verdict: Accepted)

#include <stdio.h>
#define MIN(a,b) ((a<b)?(a):(b))
#define MAX(a,b) ((a>b)?(a):(b))
 
int main() {
    int a, b, c, small, learge;
    scanf("%d %d %d", &a, &b, &c);

    small = MIN(a,b);
    learge = MAX(a,b);

    if (small <= c && c <= learge) {puts("Yes");}
    else {puts("No");}

    return 0;
