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.

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

No

Solution in JavaScript (node.js v5.12) (judge verdict: Accepted)


function Main(input) {
  // 数字
  var A = parseInt(input[0], 10);
  var B = parseInt(input[1], 10);
  var C = parseInt(input[2], 10);
  // 文字
  // var A = input[0];

  if (A < B) {
    if (A < C && C < B) {
      console.log('Yes');
    } else {
      console.log('No');
    }
  } else {
    if (B < C && C < A) {
      console.log('Yes');
    } else {
      console.log('No');
    }
  }
}
 
Main(require("fs").readFileSync("/dev/stdin", "utf8").trim().split(/\n|\s/));
