Output

Print "Yes" or "No" in a line.

Constraints

0 ≤ a, b, c ≤ 100

Sample Input 1

1 3 8

Sample Output 2

No

Solution in Ruby (judge verdict: Accepted)

def toi(a)
	b = []
	a.each do |n|
		b << n.to_i
	end
	b	
end

a = toi(gets.split)
if a[2]>a[1] && a[1] > a[0]
	print("Yes\n")
else
	print("No\n")
end
