如何找到合适的计算机作业代写机构？
- 同学朋友推荐
如果身边有同学有找代写的经验，可以让同学给你推荐。一般朋友推荐的机构还是靠谱的，有事实精力做证明。而且同学能够推荐给你肯定是比较满意的。
- 谷歌搜索、找论坛
更多的留学生是通过在谷歌上搜索关键词，如“计算机作业代写”来寻求代写服务，或者在评论网站、论坛中找资源，可供选择机构很多。但资源多了就会鱼龙混杂，需要提供资金的辨别能力。
- 看网站的内容和案例
靠谱且有规模的代写机构都是有官网的，打开代写机构的官网，查看对方的服务内容和以往的案例、代写团队资源等有效信息。最好的方式是联系网站的在线客服进一步咨询，并且咨询一些比较专业的问题来判断对方的水平是怎么样的，这样可以帮助你更深入地了解这个机构。

数据结构&算法代写实例：Data Structures And Algorithms (CITS2200 )
Q1.
(a) You are given an array of integers Aof length nand another integer q. You have to design an O(nlog n) algorithm to either find a pair of elements of Asuch that their sum is q, or report that no such pair exists.
(b) Prove that the time complexity of the algorithm you have designed in part (a) is O(nlog n). Prove the correctness of your algorithm. Intuitive arguments will suffice for both.
Q2. You have to design a list of stacks data structure. It is a linked imple-mentation of a list at the first level. A stack is associated with each node of the linked list at the second level. Every input to this data structure is a pair of integers (i, j). For inserting an item (i, j) you need to look for a node in the linked list that stores the item i, and push the item jon the stack associated with that node. In case you cannot find a node of the linked list storing item i, you have to insert a new node in the linked list and store item iin that node and item jin the associated stack. Deletion of a pair (i, j) is similar, the item jhas to be deleted from the stack of the node of the linked list that stores item i, or an error should be reported if no node of the linked list stores item i. (See the picture below).
(a) Write Java classes for implementing the list of stacks data structure. Write constructors for each class that you use. You should write correct Java code for this question and explain the code clearly in English.
(b) Write insertion and deletion methods for the list of stack data struc-ture. These need not be correct Java code, but should be clearly written if you write in English
Q3.
(a)
•Prove that n3log10 nis O(n4).
•Prove that n2log nis not O(n2).
(b) Write pseudo code or explain in your own words Prim’s minimum span-
ning tree algorithm. What is the time complexity of this algorithm?
Q4.
(a) Write pseudo code for the recursive and non-recursive depth-first search algorithms. What are the time complexities of these two algorithms?
(b) Show the execution of your non-recursive depth-first search algorithm in part (a) on the tree given below. Show the status of the stack at every step of depth-first search.
