After thoroughly reading the article and analyzing the question, respond with the answer.

Title:
Computational_complexity_theory

Context:
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 are two complexity classes between L and P?

NL and NC
