What Is the Difference Between Recursively Enumerable and Context-Sensitive Languages?

TL;DR

Recursively enumerable languages are generated by unrestricted grammar and can be recognized by Turing machines, while context-sensitive languages are generated by context-sensitive grammar and recognized by linear bounded automata. Recursively enumerable languages are a superset of context-sensitive languages, making the latter a subset of the former.

hello friends welcome to the next session in this session we are going to study another distinguish between recursively enumerable language and context sensitive language so it is going to be a very small distinguish so without wasting time let's get started with the four points of this distinguish so friends first point in recursively enumerable l...
