I was trying to solve the following problem recently online.
My question has to do various ways of solving this problem. I know I can just use breadth-first search traversal to solve the problem, but wondering if there's any other way to do this.




Given an array of elements, return the root node of a tree containing
the elements of the array progressing top down, left to right. ex:

input: [a,b,c,d,e,f,g] result tree:




 a
 / 
 b c
 / / 
 d e f g



here's my implementation of this problem for printing out in
breadth-first search order.




function graphBFS(graph, start) 
 const queue = new Queue();
 const visited = new Set([start]);
 queue.enqueue(start);
 while (queue.length) 
 const neighbors = graph.neighbors(queue.dequeue());
 for (const neighbor of neighbors) 
 if (!visited.has(neighbor)) 
 queue.enqueue(neighbor);
 visited.add(neighbor);



thanks for your feedback and help.

Function to Return a JSON Like Objects Using VBA Collections and Arrays

Image
Clash Royale CLAN TAG #URR8PPP .everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty margin-bottom:0; up vote 1 down vote favorite My goal is to create a compact function that can create a JSON Like object from JSON string. I want a function with a small footprint that I or anyone who wants to use it, can simply paste into a module and use. At 61 lines of code, I am happy with its size and portability. Here is an image of JSON Object created from string data using a ScriptControl . Although the Locals Window displays the properties and values correctly, the object itself is extremely difficult to work with. This image shows an object created using getJSONCollection . Because it is made of VBA Collections and Arrays, it is very easy to work with. Option Explicit Private Function getJSONCollection(ByVal Value As Variant, Optional ScriptEngine As Object) As Variant Const DELIMITER As String = "||" Dim col As Collection, JSON As Object, KeyNam...

Will my employers contract hold up in court?

Clash Royale CLAN TAG #URR8PPP up vote 8 down vote favorite 2 When I started a new job back in July of 2017, I signed a contract that had the following bindings or restrictions if I was ever to leave the company: Cannot work for a competitor within 25 miles of current companies location for the next two years Cannot offer my services to any organization within 25 miles of current companies location for the next two years Now, when mentioned “my services” this can be related to my profession of website design. This contract seems incredibly binding, 2 years in length, and I’m looking to see if it would actually hold up in an Arizona court. contract employment non-compete arizona share | improve this question edited Aug 7 at 15:35 feetwet ♦ 13.8k 9 37 85 asked Aug 6 at 19:05 Alex S. 46 2 What does your comp...
