a linked list and find the start node of the ring?On the Internet to see a solution: Set two pointers fast and slow, the initial values are pointing to the head, slow each time before further, fast each step forward two steps, if the linked list exists ring, then fast must first enter the ring, and slow after entering the ring, two pointers must meet. (Of course, fast head to tail is null, then a chain-free list), so you can determine whether two linked lists Intersect, the program is as follow

Using an approximate optimization is to select the closest to the current point of the non-selected points, if there are more than one of the same distance, select the BFS in turn. This total complexity is still high, so limit the number of searches, the final

Wow, that's very useful. the simplest is that you cannot determine the value of the variable when the program is running. For example, in the program we compiled in the previous lesson, you cannot determine what InputBox returns (remember the return value of Inputbox? Is the content you entered), so you cannot cope with various situations, but we use the name "box" to pack the
