The title "What should a Chinese man learn from a Western Man" does not mean to belittle Chinese men. There is no doubt that Chinese men are also worth learning from Western men. We have no intention of raising or degrading a man in a country. We just come to the truth with a rational attitude. Chinese men can compare

2. Rotation problems. The question is actually a bit vague, but it is about Rotating 90 degrees and 180 degrees. I thought there were four States to determine whether they had appeared before, but I also mentioned (plus one other not shown) in the question. That is to say, there is still a state that does not provide an image. What else is it? So I printed the image of the question through the rotation function,It is found that the

Given a linked list, determine if it has a cycle in it.
Follow up:Can you solve it without using extra space?
Question]
Determines whether a one-way linked list has loops.
[Idea]
Maintain the two pointers P1 and P2. Each time P1 moves one step forward, P2 moves two steps forward.
If P2 can catch up with P1, it indicates that the linked list has a ring.

Given A linked list, determine if it has a cycle in it.Follow up:Can you solve it without using extra space?To solve this problem requires a very clever idea, generally we would think of observing whether the linked list has repeated occurrences of the node. However, the complexity of this space is O (n), such as set to store the occurrence of the node, and then see if the next node exists in the set.A very ingenious solution is to set two pointers, a fast pointer, and a slow pointer. The quick
Determine if a list exists in a loop (not a Val loop), that is, imagine a ring, the ring may also be connected to a line, now to determine whether the linked list contains this ring.Set the speed of two nodes, slow one step, fast two steps, if there is a ring, then slow and fast will certainly enter this ring, it is now proven that once into the ring slow and fast will inevitably meet in the loop.The position of the slow in the ring is X,fast y, the ring has a m position and is set through n loo

Title Link: https://leetcode.com/problems/linked-list-cycle/To determine if there is a ring in a list, you can set two pointers, one for each advance of the first, and two for each second.For a forward two-pane pointer, you need to first determine if the forward one is NULL:
If you do not determine if it is NULL, taking two times next May cause Runtime Error.
If NULL, the link list does not exist in the ring.
If there is a ring in the list, then each advance of the two-cell pointer wi
thought: for the moment of inquiry T can shun time backwards to t+1,t+2,t+3 ... Then the T-moment and the subsequent time of the shuttle are possible, the time they can travel to insert multiset, if there is at least two elements in the Multiset value is greater than or equal to T, then the time t existence solution. It is also important to note that the moment of inquiry can be reached on the front, so we have to solve it from the back.Code:#include Copyright NOTICE: This article for Bo Maste
