Solution in Ruby (judge verdict: Accepted)

while str = $stdin.gets
  a, b, c  = str.strip.split(' ')
  a = a.to_i
  b = b.to_i
  c = c.to_i
  if a < b && b < c
    puts 'Yes'
  else
    puts 'No'
  end
#  if a > b
#    puts 'a > b'
#  elsif a < b
#    puts 'a < b'
#  else
#    puts 'a == b'
#  end
end
