-Multiple Choices Algorithm ​- by Mark Kelly+Landscaping is a great way to improve the look of any area. Believe it or not, landscaping can be a relatively simple process. Not every landscaping job requires the need to hire professionals that will cost an arm and a leg. Here are a few easy tips to help you get started.[[http://​landscaping71.webnode.com/​news/​quick-and-easy-landscaping-on-a-budget/​|Porous Pavers for Sale]]

-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: +You do not have to hire a professional to design your landscape for you, but it might be worth your time and money to quickly meet with an architect. You will get a better idea of how much your project will cost and perhaps avoid mistakes that would end up costing you money.
-1-9 items = $100 each +
-10-19 items = $97 each +
-20-29 items = $92 each +
-30-39 items = $88 each +
-40-49 items = $85 each +
-50 or more = $82 each+
  
-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. ​  +Utilize the Internet and mail-order catalogs in order to buy what you need for your landscaping project. Both of these sources are more likely to have rare plants and other products that area stores don't carry. You may also find a good deal, but be careful to pay attention to shipping costs before you purchase.
-Convert the pseudocode into code. +
-Create test data to fully test all aspects of the solution’s functionality. +
-Note:  Input data need not be validated, and the interface can be very basic. +

This is vital, so that you do not use plants that end up outgrowing their planting space, and overshadowing their neighbor plants. Plan now so you do not have to move plants around later.

-Fun with Algorithms - Mark Kelly +

-Use flow charts or N-S charts to elegantly solve the following algorithms. ​ Some are harder than others... ​ Try actually coding ​it after doing the brainwork. +
--- +
- +
-Round any decimal number UP to the next highest multiple ​of 0.25. +
- +
--- +
- +
-Convert any Roman number to decimal (e.g. MCMLXIX to 1969) - and/or vice versa +
- +
--- +
- +
-Convert any binary number to decimal. +
- +
--- +
- +
-Find the lowest (or greatest) common denominator of 2 integers (or report that there is no LCD or GCD). +
- +
--- +
- +
-List prime numbers up to 100 +
- +
--- +
- +
-Simulate the display of a single-digit liquid crystal display  +
- +
- +
-Assume there are 7 LCD bars like this +
- +
- _ +
-|_| +
-|_| +
- +
-Feed it any numeral or alphabetic character ​ in hexadecimal range (0 to F) and it should turn on the right bars.  ​(Efficiency is the key requirement here!) +
- +
--- +
- +
-Given a price including 10% GST, give the ex-tax price and the tax component, e.g. $11 inc = $10 ex + $1 GST. +
- +
--- +
- +
-Create a virtual deck of cards encoded as numbers 1 to 52.  Given any number from 1 to 52, the algorithm should return the suit and rank represented by the card. +
- +
--- +
-Create an algorithm to shuffle the virtual deck of cards  +
- +
- +
--- +
- +
-Create an algorithm to play naughts and crosses - it should be unbeatable if the algorithm plays first. +
- +

-Given an number of dollars, calculate what notes or coins need to be given as change from $100.  e.g. $67 = 1 x $20, 1 x $10, 1 x $2, 1 x $1. +
- +

-An electrical company is developing a new main-powered sensorlight with the following requirements:​ +
- +
-• It turns on its LED light for a predetermined time (e.g. 60 seconds) after sensing movement with its passive infrared (PIR) detector. +
- +
-• It does not turn the light on if its light detector senses that the room is already well illuminated (e.g. during the day) +
- +
-• While its light is on, any further movement detection resets the timer back to its starting value and the countdown starts again. +
- +
-Convert your algorithm into a working simulation of the light. ​ You will need to simulate: +
- +
-• The day/night sensor (e.g. with radio buttons) +
- +
-• The movement sensor (e.g. with a mouse click or keypress) +
- +
-• The LED light (e.g. with a shape changing its colour) +
- +
-Show the value of the countdown time onscreen to verify its behaviour. +

 +If you are doing any landscaping projects that include lumber you may want to consider waiting until winter to purchase it. Lumber is the cheapest during the winter, which could get you the highest quality lumber for the price of much lower quality lumber during the prime summer months. This might mean waiting to complete your project, but the savings will likely be worth it.
  
 +Use stones, and pebbles to decrease the amount of grass on your lawn. Stones and pebbles are attractive additions to any yard, and they do not require regular maintenance. Grass requires regular mowing, watering, and fertilizing. Reducing the amount of grass in your yard can help to save you time, and energy.
  
 +Do not plant too much of the same plant in your garden unless it is one that can withstand all type of weather conditions. If you place the same kind of plants throughout your garden and they die during an off season you will be left with a bare yard.
  
 +[[http://​fr8pals.com/​blogs/​145754/​265093/​easy-landscaping-tips-for-the-no|Gravel Porous Pavers]]There are so many ways to have a great looking yard. This article has shown you the ease and simplicity that landscaping can be. Anyone can do some simple things to have a great looking yard. As you have read here, you can make some easy changes and have a much better looking yard.
