Tarikh Chouhan Kata Solution.

Prerequisites:

• Maven
• Java

Features:

• Able to add items.
• Able to calculate the cost of items regardless if they have a special offer.
• Able to view the list of items along with their price and special offer if they have any.
• Able to add special offer to items.
• For the UI, it's an 'interactive' console in which you type the number based on the selection present.
• Coded with the Command Pattern as I thought it would be the best use case given the situation.

Instructions:

• Run mvn clean install on the pom.
• Then go into the generated target folder and run the jar file with the command java -jar ITVKata-1.0-SNAPSHOT.jar

Assumptions made:

• SKUs are not case sensitive. E.g. if item A exists, and you update the price of item a, then it'll update item A.
• Assumed prices and quantities will not go negative.
• Able to store SKUs with only capital letter
• Only integers. No decimals.
