If it's a tree then the answer is obviously diameter/2 But now it's a ring-set tree, so you just enumerate through each side of the ring and delete it and ask for the diameter to be spicy (obviously you're not going to be on one side of the ring.) And then you ask for the remaining diameter of the tree, and then the n^2 will explode. We maintain the longest chain

This is the next blog of the disruptor mode series developed by Lmax. From the previous blog, we understand what ring buffer andHow good is it?. Unfortunately, I have not mentioned how to read and write data when using disruptor. Consumerbarrier and consumer Here I will introduce it in turn, because in general th

The main idea: there is a person strange people want to pave the road, this person wants to put each ring on the stone, but the stone can not be repeatedly paved, if repeated paving, this side even if the damageAsk this person how many sides to damage, how many sides can not be paved with stoneProblem-solving ideas: no stone-paved side must be a bridge, because the bridge does not belong to any one of the ringThen judge how many sides will conflict, f

Consider the following "magic" 3-gon ring, filled with the numbers 1 to 6, and all line adding to nine.Working clockwise, and starting from the group of three with the numerically lowest external node (4,3,2 in this Example), each solution can is described uniquely. For example, the above solution can is described by the set:4,3,2; 6,2,1; 5,1,3.It is possible to complete the ring with four different totals:

The title describes a linked list that contains the ring, please find the link to the list of the entry nodes. The first step is to find the loop in the meeting point. Using P1,P2 to point to the list head, p1 each step, p2 each walk two steps, until P1==P2 find the meeting point in the ring. Step two, find the entrance to the ring. The next step, wh
