when other users access the static content, it can be returned directly from the reverse proxy server, speeding up the response speed of the Web request and alleviating the load pressure on the Web server.In addition, the reverse proxy server can also achieve load balancing functions.Because the reverse proxy server forwards the request at the HTTP protocol level, it is also called the application layer load balancer. The advantage is that the deployment is simple and the disadvantage is the bo

Title DescriptionEnter a binary tree to determine whether the two-prong tree is a balanced binary tree.Code:public class Solution {public Boolean isbalanced_solution (TreeNode root) { if (root = null) return TRUE; if (Math.Abs (GetHeight (root.left)-getheight (Root.right)) > 1) return false; Return Isbalanced_solution (Root.left) isbalanced_solution (root.right); } public int getheight (TreeNode root) { if (root = null)

define a packet with a TTL of 64. Then your data packet is forwarded 64 times, that is, after 63 intermediate routers have not reached the destination network, then your computer will show Requet time out (Request timed out). That's what the TTL means.In addition, as the TTL defined by different operating systems is different, there are generally the following rules: By default, the TTL value of a Linux system is 64 or 255,windows NT/2000/XP system has a TTL value of 128,windows 98 system with

Studying at home for just 6 weeks will not only increase your reading speed by up to 3 times times, but also achieve better understanding and deeper memory and recall capabilities.It's not difficult to run 1 miles in 8 minutes, because the world's fastest athlete can run out in 4 minutes.If you are good at swimming, you will find it easy to see the 100-metre swimming competition, the championship is not as fast as you.Some people can read 3 times times, 5 times times, or even 10 times times fast

), and the time required for each adjustment of the heap is O (logk). And a total of adjustments to n-k times. So the complexity of time isO (k + (N-K) logk), when K is far less than N, the time complexity can be approximated to O (NLOGK). In addition, the algorithm is very suitable for mass data processing, especially in memory limited. You cannot read all the data at once. When n is very large, and K is smaller, the memory is read into the K data at a time. Then each time can read into a compa

Title DescriptionEnter an array of integers to determine if the array is the result of a sequential traversal of a binary search tree. If yes, output yes, otherwise output No. Assume that any two digits of the input array are different. Analysis:The legal sequence of the sequence of BST is, for a sequence s, the last element is X (that is, the root), if the last element is removed from the sequence of T, then T satisfies: t can be divided into two segments, the previous paragraph (left sub-tree)
