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

Constraints

* 0 ≤ a, b, c ≤ 100

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.

Examples

Input

1 3 8


Output

Yes


Input

3 8 1


Output

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