Problem:
Range

Write a program which reads three integers a, b and c, and prints "Yes" if a < b < c, otherwise "No".

Input

Three integers a, b and c separated by a single space are given in a line.

Output

Print "Yes" or "No" in a line.

Constraints

0 ≤ a, b, c ≤ 100

Sample Input 1

1 3 8

Sample Output 1

Yes

Sample Input 2

3 8 1

Sample Output 2

No

Solution in Python (judge verdict: Accepted)

from __future__ import division, print_function
from sys import stdin
a, b, c = (int(s) for s in stdin.readline().split())
print('Yes' if a < b < c else 'No')
