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)

str = gets
num = str.split(" ")
a = num[0].to_i
b = num[1].to_i
c = num[2].to_i

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