This module provides simple Load Balancing (round robin scheduling and Client IP addresses) for backend servers ). Example: upstream backend { server backend1.example.com weight=5; server backend2.example.com:8080; server unix:/tmp/backend3;}

Question: Enter the root node of a binary tree to find the depth of the tree. A tree path is formed from the root node to the leaf node. The longest path length is the depth of the tree. For example, input binary tree: 10//6 14///4 12 16 Output

Description: Input: You have been given a sequence of integers.Now without actually constructing BST from the given sequence of Integers (assuming the sequence is pre-order) Determine if each node of BST has single child (either left or right but

Description: LetX[1 ..N] AndY[1 ..N] Be two arrays, each containingNNumbers already in sorted order. GiveO(LGN)-Time algorithm to find the median of all 2NElements in ArraysXAndY.   The topic is an exercise in introduction to algorithms, but it has

Description: An element in a sorted array can be found in O (log n) time via binary search. but suppose I rotate the sorted array at some unknown to you beforehand. so for instance, 1 2 3 4 5 might become 3 4 5 1 2. now devise a way to find an

I wrote a stress test script for meeting based on SIP. It can enable 50 people to enter meeting at the same time, then talk, and exit the chatting room after 12 seconds. The system waits for 8 seconds and repeats the 50 people entering the meeting

Question: Find the number of times the specified element appears in an ordered array. the time complexity is O (lgn) Ex, Array {0, 0, 3, 3, 3, 5}, 0 appears 3 times, 3 appears 5 times   Ideas: One easy way to think of is to find the specified

Question: enter a one-way linked list and output the k-th node in the list. The last 0th nodes of the linked list are the tail pointer of the linked list. The linked list node is defined as follows: Struct listnode{Int m_nkey;Listnode *

Question: Enter n integers and output the smallest k integers. For example, if you enter the 8 numbers 1, 2, 3, 5, 6, 7, and 8, the minimum four digits are 1, 2, 3, and 4. Analysis: the simplest way to solve this problem is to sort the input n
