Topic:A sorted array of the given integers, finding the starting and ending positions of the given target values. The run-time complexity of your algorithm must be the Order of O (log n). If the target is not found in the array, then [-1,-1] is returned. For example, given [5,7,7,8,8,ten] and the target value 8,return [3,4]. Idea: This topic directly uses the container to store the location where the find element is found. Remove the first and last
Non-recursive method:#include Recursive (cannot output the position of the number you want to find in the original array): #include Binary find------Find a specific number in an ordered array of ascending order
Method One 1. Apple 5s has an application for managing contacts as shown in the following figure. 2. If we enter here to find will be relatively slow, in fact, we can directly click on the "Phone" application. 3. Then you will find a "address book" at the top of the phone panel that we click on to see a lot of apps. 4. If the contact more can enter a word fast search oh. Method Two 1. The abov
MySQL branch), Instead of the original MySQL. In addition, so you run Yum install MySQL is equivalent to running yum install MariaDB But for MARIADB, the direct installation of MARIADB is not going to run as a service, because you only install MARIADB client, so you also need to download a series of MARIADB components than Mariadb-server (server side). Workaround: Run the yum Search all MariaDB A series of packages are then listed Mariadb-bench mariadb-devel mariadb-embedded mariadb-server m

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 the ring, the two pointers must meet each other. (Of course, if the first line to the end of fast is null, It is a loop-free linked list)
