Write a function that will output breadth first search and depth first search order for a tree data structure. The tree shall only contain integers for it’s node. I expect the following: (1) A PHP class that represents a tree data structure. (2) A PHP function (BFS) that takes a tree as input and output the ordering of a breadth first search on the command line. (3) A PHP function (DFS) that will output a depth first search on the same tree (4) I should be able to run the class on the command line Notes: - Ensure that your function can handle cycles - Ensure that the nodes can only be integer When you apply to this job, answer the following questions. IF YOU DO NOT ANSWER THESE QUESTIONS, YOU WILL NOT BE CONSIDERED. (1) What is the complexity (O runtime) of BFS and DFS? (2) What is the difference between a stack and queue data structure? (3) How many hours will it take to do this job?

Hi, I am placing my bid on your project because I have read the requirements and I am confident enough with my PHP and Algorithmic skills. I have implemented the Tree data structure before and also those algorithms such as Depth First Search and Breadth First Search. I am focused mostly on doing computer science homework here in freelancer.com and I would like to help you get this project done if you would give me the opportunity. I am a computer science professor and practitioner and this assignment is one of the fields that I teach very well so I can assure you an accurate result.

Hello, It's essentially very easy task for me, I will write this class for you in a no time. Basically, I have already wrote BFS and DFS many times, so I have only to write appropriate CLI representation of graphs, and inputs (btw, how should we input the tree, in what format and is it from a file, standard input, or hardcoded?) I have more than 5 years as PHP developer, and more than 10 years in programming (I was also teaching programming languages, so I can explain you these algorithms if you want). Now, answers to your questions: (1) What is the complexity (O runtime) of BFS and DFS? O(V+E) - V stands for vertices and E for Edges. (2) What is the difference between a stack and queue data structure? Stack is LIFO (last in first out), and queue is FIFO (first in first out). (3) How many hours will it take to do this job? Less than 1, since I already have wrote algorithms, input and output can take from 30 - 50 minutes to develop. Contact me for further details. Kind regards, Nikola

I am a experienced php/java programmer ill do this for you 1) What is the complexity (O runtime) of BFS and DFS? BFS: Worst case O(|E| + |V|) DFS: Worst case O(|E| + |V|) (2) What is the difference between a stack and queue data structure? Stack: First In Last Out, Queue: First In First Out (3) How many hours will it take to do this job? Need More details
