SExpressionCalculator

I was tasked to create a simple integer calculator that can process a syntax that resembles S-expressions which can take english like expressions and return their result and that is capable of processing nested expressions.

How to compile

Requirements:

• Java 17
• Maven

You can compile the project using Maven by running the following while in the project root folder:

mvn package

How to execute

Once compiled, you can run the jar as follows:

java -jar ./target/SExpressionCalculator-1.0-SNAPSHOT-shaded.jar "<expression>"

# For example
java -jar ./target/SExpressionCalculator-1.0-SNAPSHOT-shaded.jar "(add 12 12)"

An expression is formed the following way: (function integer/nested expression integer/nested expression)

Available functions:

Name	Syntax Example	Expected Result
Add	(add 10 10)	20
Multiply	(multiply 10 5)	50
Subtract	(subtract 100 25)	75
Exponent	(exponent 2 5)	32

Extra credit:

• Implemented subtract and exponent function types since it was easy to extend my base code to cover these.
• Made it so you can specify as many arguments to a function as you want, for example: "add 10 20 30 40 50"
