约瑟夫环是一个很有意思的算法。大意就是：罗马人占领了乔塔帕特，41个人藏在一个山洞中躲过了这场浩劫。这41个人中，包括历史学家约瑟夫(Josephus)和他的一个朋友。剩余的31个人为了表示不想罗马人屈服，决定集体自杀。大家决定了一个自杀方案，所有这41个人围成一个圈，由第1个人开始顺时针报数，每报数为3的人立刻就自杀，然后再由下一个人重新开始报数，仍然是每报数为3的人就立刻自杀，直到所有人都自杀身亡为止。 约瑟夫和他的朋友并不想自杀，于是约瑟夫想到了一个计策，他们两个同样参与到自杀方案中，但是最后却躲过了自杀。 算法思路： 41个人围成一个圈报数，数到3的人就立刻自杀。约瑟夫和朋友想活下来的话，也就是当39个人都数到3并立刻自杀后，约瑟夫和朋友就不遵守自杀的约定，他们就活了下来，也就是他们俩站的初始位置要正确。 现在我们用一个int型数组来存放41个人，数组元素初始值都为0，当第几个数到3的人自杀后，我们用约瑟夫环数标记为几，并记录自杀者的初始位置。当41个人全部自杀后，我们遍历找出倒数前两个自杀的初始位置后，这两个

RingThe definition of is similar to the interchangeable group, but adds another operation "·" on the basis of the original "+" (note+ And. It is not generally known as addition and multiplication ). In abstract algebra, ResearchRingIsRing Theory. Definition The Set R and binary operations defined on it + and (r, +, ·) constituteRingIf they meet the following requirements: (R, +) forms an exchange group. Its unit is calledZero Element, As '0 '. That is: (R, +) is closed (A + B) = (B +

Definition: Circular chain list: A node in a list with the next pointer to a previously existing node, causing a loop in the list. Question 1: Determine if there is a ring #include Question 2: Find the starting point for this ring Input: A->b->c->d->e->f->g->h->i->j->k->d Output: D Analysis: When fast and slow meet, slow definitely did not traverse the list, and fast in the

particular buffer to be mapped to different content by different users. As with dispersion, this situation should also be avoided, so a good hashing algorithm should be able to minimize the buffering load. In a distributed cluster, adding or removing machines, or automatically leaving the cluster after a machine failure, is the most basic function of distributed cluster management. If the use of commonly used hash (object)%n algorithm, then after the machine is added or deleted, many of

Written in front: The sword refers to the offer, interview, is a classic problem, today to summarize, in fact, from this topic, can be resolved, extended a number of issues, such as: whether there is a linked list, if there is a ring, to find the link in the ring of the entry node, the length of the ring is how much.

Recently began to seriously learn the algorithm, with the Sedgewick of the "algorithms". Much of the content is the same as the data structure, the difference is the content of the algorithm more explanation. I often keep track of the difficulties I encounter in learning algorithms and how to solve them.The problem of judging the existence loop is encountered when learning the topological sort. The problem of judging the ring is divided into the direc

2018-01-13 20:55:56The algorithm of Floyd judgment Circle (Floyd Cycle Detection algorithm), also known as the Turtle Rabbit Race algorithm (tortoise and Hare algorithm), is a finite state machine can be , an iterative function or a chain list to determine whether a ring exists , and the algorithm for the starting and length of the ring is obtained. The algorithm, according to Gartner, was invented by Amer
