## Constructing a State Diagram for a Sequence Detector

### Overview
This exercise involves building a state diagram for a finite-state machine (FSM) used as a sequence detector. The FSM processes a 1-bit input \( v \) and produces a 1-bit output \( g \).

### Functionality
- **Input:** A 4-bit sequence.
- **Output:** The FSM sets the output to 0 for the first three bits of each sequence. It outputs 1 on the fourth bit only if the sequence matches one of these binary strings: `0000`, `0011`, or `0111`.
- **Type:** This FSM is a Mealy-type machine, meaning the output is determined by both the current state and the current input.
- **Reset:** The machine resets to the initial state after processing each 4-bit sequence.
- **Non-overlapping Patterns:** The input sequences do not overlap during processing.

### Sample Behavior
To illustrate how this FSM functions, consider the following example. Spaces are inserted between each 4-bit sequence for clarity. Note that this example demonstrates the machine's ability to process and reset after each sequence, ensuring recognition of the specified patterns without overlap.

**Finite State Machine Example**

This example demonstrates some sample behavior of a finite state machine (FSM). Spaces are added between each 4-bit input sequence for clarity.

- **Input Sequence (v):** 1000 0000 0000 0111 0101 0011
- **Output Sequence (g):** 0000 0001 0001 0001 0000 0001

**Task: FSM State Reduction**

Your task is to fully reduce the number of states in your FSM and construct the reduced state table.
