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)

number = raw_input().split(" ")
a = int(number[0])
b = int(number[1])
c = int(number[2])
if a < b < c:
    print "Yes"
else:
    print "No"
