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)

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