answer:Here's the code to create the 8x8 chessboard with labels on all four sides: ```python # Create a function to print the chessboard with loop structures def print_chessboard(): for row in range(1, 11): if row == 1 or row == 10: labels = " ABCDEFGH " print(labels) else: line = "" for col in range(1, 11): if col == 1 or col == 10: line += str(9 - row) else: line += str(9 - row) + chr(64 + col) print(line[:9] + line[-1]) # Call the function print_chessboard() ``` The above code will print the chessboard with labels. For the bonus which requires a loop for printing the chessboard, the entire chessboard is inside a loop structure printing it 11 times: ```python # Count the number of prints n_prints = 0 # Outer loop for i in range(10): # Printing the entire chessboard and labels within loop structures if n_prints < 10: print_chessboard() n_prints += 1 ```

answer:1. T(R(CB(remoteCall()))): In this order, Timeout (T) is applied first, followed by Retry (R), and then Circuit Breaker (CB). This ensures that each individual call adheres to the response time SLA while also allowing for retries only if the timeout limit is not breached. The circuit breaker prevents overwhelming the called service with excessive requests. 2. CB(T(R(remoteCall()))): In this order, Circuit Breaker (CB) is applied first, followed by Timeout (T), and then Retry (R). This ensures that the called service is protected from being overwhelmed by requests while also adhering to the response time SLA for each call. The retries happen only if the timeout limit is not breached.

answer:To create a program as described, you can use a popular Python library called OpenCV. Here's some sample code for the program. This code shows a simple implementation of requirements and may require further polishing for optimal user experience: ```python import cv2 import numpy as np import math drawing = False ix, iy = 0, 0 color = (0, 255, 0) width = 5 points = [] completed_lines = False def draw_line(event, x, y, flags, param): global ix, iy, drawing, points, image_with_lines, completed_lines if event == cv2.EVENT_LBUTTONDOWN: if not completed_lines: points.append((x, y)) cv2.circle(img, (x, y), width, (255, 0, 0), -1) if len(points) == 3: completed_lines = True elif len(points) == 3: drawing = True image_with_lines = img.copy() ix, iy = x, y elif event == cv2.EVENT_MOUSEMOVE: if drawing: dx, dy = x - ix, y - iy moved_points = [(point[0] + dx, point[1] + dy) for point in points] image_with_lines = img.copy() cv2.line(image_with_lines, moved_points[0], moved_points[1], color, width) cv2.line(image_with_lines, moved_points[1], moved_points[2], color, width) elif event == cv2.EVENT_LBUTTONUP: if drawing: drawing = False dx, dy = x - ix, y - iy points = [(point[0] + dx, point[1] + dy) for point in points] img = image_with_lines def angle(points): a = np.array([points[0][0] - points[1][0], points[0][1] - points[1][1]]) b = np.array([points[2][0] - points[1][0], points[2][1] - points[1][1]]) cos_angle = np.dot(a, b) / (np.linalg.norm(a) * np.linalg.norm(b)) angle = np.arccos(cos_angle) return round(np.degrees(angle), 2), round(180 - np.degrees(angle), 2) image_path = input("Enter the path to your image: ") img = cv2.imread(image_path) cv2.namedWindow('Image') cv2.setMouseCallback('Image', draw_line) while True: if len(points) >= 2: cv2.line(img, points[0], points[1], color, width) if len(points) == 3: cv2.line(img, points[1], points[2], color, width) if completed_lines: internal_angle, external_angle = angle(points) print("Internal Angle: ", internal_angle, " External Angle: ", external_angle) if drawing: cv2.imshow('Image', image_with_lines) else: cv2.imshow('Image', img) key = cv2.waitKey(1) & 0xFF if key == ord('r'): color = (0, 0, 255) elif key == ord('g'): color = (0, 255, 0) elif key == ord('b'): color = (255, 0, 0) elif key == ord('k'): color = (0, 0, 0) elif key == ord('w'): width += 1 elif key == ord('s'): width -= 1 elif key == 27: break cv2.destroyAllWindows() ``` This program first imports necessary packages, sets global variables, and defines some helper functions. The `draw_line` function is the main mouse event handler that performs the drawing and moving of lines on the image. The `angle` function calculates the internal and external angles between the two lines. The main loop reads an input image, displays it using OpenCV, and calls the mouse event handler to handle the interaction. Please note that the command documentation may change depending on the OpenCV version used. In the sample code above, lines 26 and 63 are examples of such differences. The user can press "r", "g", "b", or "k" to change the color and "w" or "s" to change the line width. The result of the measurement will be printed in the console when the user completes the angle drawing. The code can be further enhanced with more functionality, better input validation, and a more user-friendly interface.
