Two-point SearchThe binary lookup principle is simple:In an ordered array (this article discusses ascending, descending)Starting from the element in the middle of the array, if A[MID] is larger than the found element key, then find it in a[0] to a[mid-1] and vice versa in a[mid++] to a[a.lenth-1].From this point of view, the meaning of recursion is very strong ah, of course, can also be used in a non-recursive way, more efficient, meaning that binary

are taken from a node (the node with an outbound degree of 0 has no way to go), the node is considered as the final safe node. If it cannot be stopped, it is on a ring, that is, an insecure node. Stop in the natural K step to reach the security node, return the index value of all the security nodes that meet the requirements. The essence is to find nodes that are not on the loop in a directed graph.
Solution: DFS. nodes can be classified by dyeing. T
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 whether the linked list has a ring. The method is as follows:Set two pointers (fast and sl
