Do you mind switching to another blogger ~~ Http://blog.csdn.net/thestoryofsnow/article/details/6822576 ~ Question: How can we check whether a linked list has a ring? If so, how can we determine the starting point of the ring. The basic idea of the solution can be explained by running examples. If two people start at the same time, if the track has a ring, the fa

Given a single linked list, give only the pointer h:1, how to determine whether there is a ring?2, how to know the length of the ring?3, how to find out where the ring connection point?4.

Http://beyrens.blog.163.com/blog/static/9589445220081013332452/ First, how to determine whether a linked list has a ring: Set two pointers (fast and slow). The initial values all point to the header. Slow moves one step forward each time, and fast moves two steps forward each time. If the linked list has a ring, fast must first enter the ring, when slow enters th

SQL Server ring buffers (ring buffer)--loop buffering in AlwaysOn applicationsYou can get some diagnostic AlwaysOn information from the SQL Server ring buffer, or dynamically manage views from sys.dm_os_ring_buffers. The ring buffer is created when SQL Server starts and records alarms within the SQL Server System for i

There is a single-chain table, where there may be a ring, that is, the next of a node points to the previous node in the linked list, so that a ring is formed at the end of the linked list. Problem: 1. How to determine whether a linked list is such a linked list?If the linked list contains an existing ring, what is the entry point of the

From http://blog.csdn.net/wuzhekai1985/article/details/6725263----------------------Question 1, how can I tell if a ring exists in a linked list? That is, the ring from E to r?Set Slow/fast two pointers, starting at the beginning of the list, where fast pointer fast speed moves each length of 2,slow one at a time. If there is no ring, fast cannot coincide with th

1. Ring bufferThe benefit of the buffer is the space exchange time and the coordination of slow and fast threads. Buffers can be used in a number of design methods, here to say a few of the design of the ring buffer, can be seen as several types of ring buffer mode. The design of the ring buffer involves several points

There is a single-chain table, which may have a ring, that is, the next of a node points to the node before it in the linked list,This forms a link at the end of the linked list. Problem:1. How to determine whether a linked list is such a linked list?2. If the linked list contains an existing ring, how can we find the entry point of the ring?Answer:1. Determine

There are several solutions to determine whether a linked list has a ring:1. In a traversal table, a node that has been traversed is placed in a hash table. If a node already exists in a hash table, a ring exists. Time: O (n) Space: O (N)2. Reverse the linked list. Time O (N), Space O (1), use three pointers.
