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: Wrong Answer)

def max(a, b, c)
    if a < b && b < c
        puts "Yes"
    else
        puts "No"
    end
end

print max(1, 3, 8)
print max(3, 8, 1)
