Problem:
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

Solution in C (GCC 5.4.1) (judge verdict: Accepted)

int main(void)
{
    int a,b,c;
    int score = 0;
    
    scanf("%d %d %d",&a, &b, &c);
    
    if(a > c && b > c)
        score = 0;
    else if(a < c && b < c)
        score = 0;
    else
        score = 1;

    
    if(score == 0)
        printf("No\n");
    else
        printf("Yes\n");
    
    return 0;
}
