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)

line = gets
input_a, input_b, input_c = line.split(" ")
input_a = input_a.to_i
input_b = input_b.to_i
input_c = input_c.to_i
if input_a < input_b && input_b < input_c then
  puts 'Yes'
else
  puts 'No'
end
