从数组中检测圆的相交

class Circle:
    def __init__(self, center, radius):
        self.center = center
        self.radius = radius

def detect_intersecting_circles(circles):
    intersecting_circles = []
    for i in range(len(circles)):
        for j in range(i+1, len(circles)):
            circle1 = circles[i]
            circle2 = circles[j]
            distance = ((circle1.center[0] - circle2.center[0])**2 + (circle1.center[1] - circle2.center[1])**2)**0.5
            if distance < circle1.radius + circle2.radius:
                intersecting_circles.append((circle1, circle2))
    return intersecting_circles

# 示例用法
circles = [Circle((0, 0), 1), Circle((1, 1), 2), Circle((2, 2), 1.5)]
intersecting_circles = detect_intersecting_circles(circles)
for circle_pair in intersecting_circles:
    print("相交的圆：", circle_pair[0].center, circle_pair[1].center)
