Block 1: Importing Modules and Defining Test Cases

```python import unittest import generative class GenerativeTest(unittest.TestCase): def test_flatten_image(self): test1 = [[1]] self.assertEqual([1], generative.flatten_image(test1)) test2 = [[1, 0], [1, 1]] self.assertEqual([1, 0, 1, 1], generative.flatten_image(test2)) test3 = [[1, 0, 1], [1, 0, 1], [1, 1, 0]] self.assertEqual([1, 0, 1, 1, 0, 1, 1, 1, 0], generative.flatten_image(test3)) def test_unflatten_image(self): test1 = [1] self.assertEqual([[1]], generative.unflatten_image(test1)) test2 = [1, 0, 1, 1] self.assertEqual([[1, 0], [1, 1]], generative.unflatten_image(test2)) test3 = [1, 0, 1, 1, 0, 1, 1, 1, 0] self.assertEqual([[1, 0, 1], [1, 0, 1], [1, 1, 0]], generative.unflatten_image(test3)) def test_check_adjacent_for_one(self): test = [0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 1, 1, 1, 1, 1] self.assertEqual(False, generative.check_adjacent_for_one(test, 0)) self.assertEqual(False, generative.check_adjacent_for_one(test, 1)) self.assertEqual(False, generative.check_adjacent_for_one(test, 2)) self.assertEqual(True, generative.check_adjacent_for_one(test, 3)) self.assertEqual(False, generative.check_adjacent_for_one(test, 4)) self.assertEqual(False, generative.check_adjacent_for_one(test, 5)) self.assertEqual(True, generative.check_adjacent_for_one(test, 6)) self.assertEqual(True, generative.check_adjacent_for_one(test, 8)) self.assertEqual(True, generative.check_adjacent_for_one(test, 9)) self.assertEqual(True, generative.check_adjacent_for_one(test, 10)) ```

This block imports the `unittest` module and a module named `generative`. It defines a test class `GenerativeTest` that contains several test cases for functions in the `generative` module. These test cases check the functionality of the generative image manipulation functions.

Block 2: Type Hinting and Function Definitions

```python from __future__ import annotations from typing import List # Function definitions for image manipulation def flatten_image(image: list[list[int]]) -> list[int]: """ Flattens a 2D list into a 1D list. :param image: 2D list of integers representing an image. :return: 1D list of integers representing a flattened image. """ return [pixel for row in image for pixel in row] def unflatten_image(flat_image: list[int]) -> list[list[int]]: """ Unflattens a 1D list into a 2D list. :param flat_image: 1D list of integers representing a flattened image. :return: 2D list of integers. """ image = [] row_length = int((len(flat_image))**0.5) for row in range(row_length): list_of_pixel = [] for i in range(row_length): list_of_pixel.append(flat_image[i + (row * row_length)]) image.append(list_of_pixel) return image def check_adjacent_for_one(flat_image: list[int], flat_pixel: int) -> bool: """ Checks if a pixel has an adjacent pixel with the value of 1 in a 1D list. :param flat_image: 1D list of integers representing a flattened image. :param flat_pixel: Integer representing the index of the pixel in question. :return: Boolean. """ image_size = int((len(flat_image))**0.5) row = flat_pixel // image_size column = flat_pixel % image_size # Pixels to check in the 1D list to_check = [] # Check above if row > 0: to_check.append(flat_pixel - image_size) # Check below if row < image_size - 1: to_check.append(flat_pixel + image_size) # Check left if column > 0: to_check.append(flat_pixel - 1) # Check right if column < image_size - 1: to_check.append(flat_pixel + 1) # Return True if any adjacent pixel has the value of 1 return any(flat_image[i] == 1 for i in to_check) def pixel_flip(lst: list[int], orig_lst: list[int], budget: int, results: list[list[int]], i:int =0) -> None: if budget == 0: return if i == len(orig_lst): return pixel_flip(lst, orig_lst, budget, results, i + 1) if orig_lst[i] == 0: if check_adjacent_for_one(orig_lst, i) > 0: copy = list(lst) copy[i] = 1 results.append(copy) pixel_flip(copy, orig_lst, budget-1, results, i+1) ```

In this block, the code first specifies type hinting using annotations. It then defines several functions used for image manipulation, including flattening and unflattening images, checking adjacent pixels for a specific value, and pixel flipping. These functions form the core of the image generation process.

Block 3: Writing Images to Files

```python def write_image(orig_image: list[list[int]], new_image: list[list[int]], file_name: str) -> None: f = open(file_name, 'w') height = len(orig_image) width = len(orig_image[0]) for i in range(height): for j in range(width): if orig_image[i][j] != new_image[i][j]: f.write('X') else: f.write(str(orig_image[i][j]) f.write('\n') f.close() def generate_new_images(image: list[list[int]], budget: int) -> list[list[list[int]]]: flattens = flatten_image(image) flippeds = [] pixel_flip(flattens, flattens, budget, flippeds) results = [] for flipped in flippeds: results.append(unflatten_image(flipped)) return results ```

This block contains two functions: `write_image` and `generate_new_images`. The `write_image` function is responsible for writing the differences between the original and new images to a file. The `generate_new_images` function generates new images by flipping pixels while adhering to a budget constraint.

Block 4: Main Function and Execution

```python def main(): lst = [[1,0,0],[1,0,0],[1,1,1]] results = [] pixel_flip(flatten_image(lst), flatten_image(lst), 3, results) for result in results: print(result) pref = 'file' for i in range(len(results)): write_image(lst, unflatten_image(results[i]), pref + str(i) + '.txt') if __name__ == '__main__': main() ```

The `main` function is responsible for executing the image generation process. It defines a sample image, calls the `pixel_flip` function to generate new images, and writes these images to files. This block also checks whether the script is executed as the main program and, if so, runs the `main` function.
