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: Wrong Answer)

a = 0
b = true

gets.split(" ").each{|e|
    e = e.to_i
    b = false if e < a
    a = e
}

if b
  puts "Yes"
else
  puts "No"
end
