Find regular grammars generating the languages represented by the following finite automata.

Transcribed Image Text:The image contains two directed graphs, often used to represent state transitions in automata theory or graph theory studies. Here's a detailed description:
1. **Graph at the Top:**
- **Nodes:** There are four nodes labeled A, B, C, and D.
- **Edges:**
- An edge labeled "a" connects A to B.
- An edge labeled "b" connects A to D.
- An edge labeled "a" connects B to C.
- An edge labeled "b" connects B to D.
- An edge labeled "b" connects D to A.
- An edge labeled "a" connects D to C.
This graph represents a finite state machine with transitions based on inputs 'a' and 'b'.
2. **Graph at the Bottom:**
- **Nodes:** There are four nodes labeled S, A, C, and B.
- **Edges:**
- An edge labeled "a" connects S to A.
- An edge labeled "b" connects A back to itself (a self-loop).
- An edge labeled "a" connects A to C.
- An edge labeled "b" connects C back to itself (a self-loop).
- An edge labeled "b" connects C to B.
- An edge labeled "a" connects C to B from S.
- An edge labeled "a, b" connects S directly to B.
This graph shows a state transition system with self-loops and multiple paths leading to node B.
These graphs are useful for illustrating how states transition based on different inputs, a fundamental concept in computer science related to automata and language processing.
