-Multiple Choices Algorithm - by Mark Kelly+How to Find a Landscaper for Your HOA
  
-Another in the Fun with Algorithms series +[[http://​www.unlimitedlandscaping.com|flower and weed control atlanta 
- +  
-Stuff Pty Ltd sells stuff. The unit cost of the stuff varies according to the quantity ordered. Customers can order any number ​of items.  Stuff Pty Ltd use this scale: +Home Owner’s Associations feature a very important role in the development of communities. They have great responsibilities including managing the assets ​of the community, and assigning ​the right people for major roles in the association. One of the responsibilities of the HOA is community development that involves landscaping. Here are some tips to help you hire a good landscaper for your HOA. 
-1-9 items = $100 each +  
-10-19 items = $97 each +Look for an all-rounder 
-20-29 items = $92 each +  
-30-39 items = $88 each +Certain landscape firms have contractors and professionals who handle everything associated with landscaping your community. This involves landscaper, gardeners, irrigation crew, and water companies ​to contribute towards ​the entire process ​of landscaping. Hire a company that undertakes ​all of these tasks. It would be cost-effective, and will save you a lot of time wasted in worrying about different contractors. 
-40-49 items = $85 each +  
-50 or more = $82 each +Good reviews often come from successes 
- +  
-Task: using pseudocode, create an algorithm ​to calculate ​the unit cost of the items at different quantities. Then calculate ​a total cost with 10% GST added. ​  +Check the internet for reviews of different landscape firms. You can also contact your neighboring communities to inquire about other landscapers. It is likely that you will come across a list of landscapers who have been given great reviews for their work. Visit other communities to gain a perspective about their work, and draw up a list of potential landscape firms you would like to hire. 
-Convert the pseudocode into code. +  
-Create test data to fully test all aspects ​of the solution’s functionality. +First meeting reveals a lot of information 
-Note:  Input data need not be validated, and the interface can be very basic. +  
-  +When you meet with people from different landscaping companies, be alert as you request for more information about their services. Evaluate their responses and analyze if they respond well to you. Make a mental note of how responsive they are when you contact them, as that would tell you if they communicate matters to you well in time. Check if they are well-adapted to technology so that they can stay in touch with the HOA through emails, and social media to post updates about their work. 
-Sample VB2010 solution +  
-Public Class Form1 +If you find a contractor that satisfies the needs of the community ​and the HOA, with skills ​and service, then hire immediately. It is alright if a few people are not happy about it. Make a judgment based on the majority poll at the HOA, and stick to it as you can derive good results from a great landscape contractor.
