input: Background: Similarly, it is not known if L (the set of all problems that can be solved in logarithmic space) is strictly contained in P or equal to P. Again, there are many complexity classes between the two, such as NL and NC, and it is not known if they are distinct or equal classes.
  Question: What variable is associated with all problems solved within logarithmic space?
  Answer:<extra_id_0>.
output: <extra_id_0> L<extra_id_1>
