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)

input_data = STDIN.gets
a_b_c = input_data.split(" ")
a = a_b_c[0].to_i
b = a_b_c[1].to_i
c = a_b_c[2].to_i

if a < c && b < c then
  if a < b then
    print "Yes\n"
  else
    print "No\n"
  end
else
  print "No\n"
end
