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

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 Go (1.6) (judge verdict: Accepted)

package main

import (
	"fmt"
)

func main() {
	var intArray []int

	n := 3

	intArray = make([]int, n)
	i := 0
	for i = 0; i < n; i++ {
		fmt.Scanf("%d", &intArray[i])
	}
	if (intArray[2] > intArray[0] && intArray[2] < intArray[1]) || (intArray[2] > intArray[1] && intArray[2] < intArray[0]) {
		fmt.Println("Yes")
	} else {
		fmt.Println("No")
	}
}
