To convert the given RLE (Run Length Encoded) string of a Game of Life pattern to a numpy array, we'll follow these steps: 1. Parse the RLE string to understand how the pattern is encoded. 2. Implement the `rle_to_arr` function that takes the RLE string, height `h`, and width `w` of the desired output numpy array. 3. Decode the RLE string and populate the numpy array accordingly. Parsing RLE: - The RLE encoding describes the pattern in a compact form. Each part of the RLE consists of a number (optional, defaults to 1 if absent) followed by a character. The character indicates what to do: - 'b' means a run of dead cells (0s). - 'o' means a run of alive cells (1s). - '$' indicates the end of a line, moving down to the next row. - '!' marks the end of the pattern (not present in your string but typically used in RLEs). Let's implement the `rle_to_arr` function:

Call the function `rle_to_arr(string, h, w)` which should return a numpy array with .shape (h,w). Fill the array with 1s, and empty with 0.
To convert the given Game of Life pattern in RLE (Run Length Encoded) format to a NumPy array, we need to first understand the RLE format and then write a function to parse it into a grid. The given RLE string encodes a pattern where `$` is used to denote the end of a line (row), `b` represents a dead cell, and `o` represents a live cell. Numbers before a character indicate how many of that character there are in a row. If there's no number, it means there's just one of that character. Below is the Python function `rle_to_arr` that takes an RLE string and dimensions (height `h` and width `w`) as input and returns a NumPy array with the specified dimensions, filled according to the pattern:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 | import numpy as np def rle_to_arr(rle_string, h, w): # Initialize an empty array. arr = np.zeros((h, w), dtype=int) # Split the RLE string into lines. lines = rle_string.split('$') row = 0 for line in lines: col = 0 while col < len(line): c = line[col] # Determine the run length (default is 1). run_length = 1 if c.isdigit(): # Extract the full number. num_start = col while col + 1 < len(line) and line[col + 1].isdigit(): col += 1 run_length = int(line[num_start:col+1]) col += 1 c = line[col] # Fill the array based on the character. if c == 'b': # 'b' means dead cells, which are already 0 in the initialized array. pass elif c == 'o': arr[row, col:col+run_length] = 1 col += run_length row += 1 return arr # Example usage: rle_string = "26$13b2o$14bo$14bobo$15b2o14$31b2o$30b2o$32bo13$46b2o$45b2o$47bo13$61b2o$60b2o$62bo4$52b2o$52b2o$71bo$66b2ob3o$66bobobo$68bo$67b2o3$76b2o$60b3o12b2o10bobo$52b3o7bo14bo8bo2bo4bo$51bo3bo5bo10b2o11b2o5b2o$50bo5bo15bobo8b2o3bo8b2o$51bo3bo11b2o6bo9b2o10b2o$52b3o8b2obo2bo2bo2bo10bo2bo$52bo2bo7b2o2b2o6bo11bobo$53b3o16bobo$53b2obo15b2o$54bobo$55bo3$52b2o3b2o$52bobobobo$53b5o$54b3o$55bo7$54b2o$54b2o!" h, w = 100, 100 # Example dimensions; adjust as necessary for the pattern arr = rle_to_arr(rle_string, h, w) print(arr.shape) # Output should be (100, 100) |

To convert the given Game of Life pattern from RLE (Run Length Encoded) format to a NumPy array, we need to first understand the RLE format and then write a function to decode this format into a 2D array of the specified height (`h`) and width (`w`). The provided RLE string represents the pattern, where `$` separates rows, numbers before a letter indicate the number of times that letter should be repeated (with `b` representing a dead cell or 0, and `o` representing a live cell or 1), and `!` marks the end of the pattern. Here's how to do it: 1. Install NumPy if you haven't yet. You can do this using pip:

To convert a Run Length Encoded (RLE) representation of a Game of Life pattern to a numpy array, you can follow these steps: 1. **Initialize an empty numpy array** with the given height `h` and width `w`, filled with zeros. 2. **Parse the RLE string**: The RLE string consists of numbers followed by characters (`b` for empty space, `o` for a live cell, `$` for a new line). Numbers indicate how many times the following character repeats. If there's no number, it means the character repeats once. 3. **Fill the numpy array** accordingly: Iterate through the parsed RLE string, updating the numpy array with 1s for live cells and leaving 0s for empty spaces. Here's a Python function that does this:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 | import numpy as np def rle_to_arr(rle_string, h, w): # Initialize an empty array with given dimensions, filled with zeros arr = np.zeros((h, w), dtype=int) # Current position in the array x, y = 0, 0 # Parse the RLE string count = '' for char in rle_string: if char.isdigit(): # If the character is a digit, add it to the count count += char else: # If the character is not a digit, process the count (if any) # and the character if count == '': num = 1 else: num = int(count) count = '' # Reset count for the next sequence if char == 'b': # b for empty space, just move x x += num elif char == 'o': # o for a live cell, fill the array with 1s and move x for _ in range(num): arr[y, x] = 1 x += 1 elif char == '$': # $ for a new line, move y and reset x y += num x = 0 return arr # Example usage (with a small example for brevity) rle_string = "3o$2bo$3b2o!" h, w = 3, 4 # Height and width of the resulting array arr = rle_to_arr(rle_string, h, w) print(arr) |
