This is a set of classes and functions, not part of the standard library, that I have found it helpful to keep around.

## Stopwatch

This is a class that allows you to determine the execution time of an algorithm.
You can get specific resolutions of time through their own get functions, all of which return double.
However I have built it a function, getStr(), that automatically chooses the best resolution and returns both the number and resolution as a string.

```Java
	Stopwatch timer = new Stopwatch();
	timer.start();
	//Code to time here
	timer.stop();
	System.out.printf("It took %s to run this algorithm", timer.getStr());
	//You could also do something like this if you prefered
	System.out.printf("It took %f milliseconds to run this algorithm", timer.getMilli());
```

## Algorithms

This is a class that contains many different algorithms that I have found it useful to keep around. This is used extensively in my [Project Euler](https://git.mattrixwv.com/ProjectEuler/ProjectEulerJava) project.
All methods are overloaded to allow for using Integer, Long, and BigInteger types.
