示例1: cloneLinkedList
# 需要导入模块: from Point import Point [as 别名]
# 或者: from Point.Point import prev [as 别名]
def cloneLinkedList(self):
cursor = self.HEAD
# make a copy of the head first:
newHead = Point(cursor.x, cursor.y)
newHead.ear = cursor.ear
newHead.name = cursor.name
# use a loop to create clones of the rest of the points:
cursor = cursor.next
newCursor = newHead
while cursor is not self.HEAD:
newPoint = Point(cursor.x, cursor.y)
newPoint.ear = cursor.ear
newPoint.name = cursor.name
# link the previous point to the new one:
newCursor.next = newPoint
newPoint.prev = newCursor
cursor = cursor.next
newCursor = newPoint # same as: newCursor = newCursor.next
# finally, link the new head and tail before returning the head:
newHead.prev = newCursor
newCursor.next = newHead
return newHead, self.SIZE
