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)

a, b, c = gets.chomp.split("\s")
a, b, c = a.to_i, b.to_i, c.to_i

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