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: WA: Presentation Error)

a, b, c = gets.split(" ")

if ((a.to_i < b.to_i) && (b.to_i < c.to_i)) then
  puts " Yes"
else
  puts "No"
end
