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 Ruby (judge verdict: Accepted)

s, t, u = gets.split(" ")
a = s.to_i
b = t.to_i
c = u.to_i

if a < b && b < c
  puts "Yes"
else
  puts "No"
end
