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)

# multi_input pattern
ins = gets.chomp!.split(" ")
ins.map!(&:to_i)

if (ins[0] < ins[1]) && (ins[1] < ins[2]) then
	puts "Yes"
else
	puts "No" 
end
