kleines Filmröllchen 3d0da734ee AK: Allow Statistics to be used with any container type 
This not only facilitates using non-owning types, but also those that
cannot be default-constructed.

Staubfinger da1023fcc5 AK: Add thresholds to quickselect_inline and Statistics::Median 
I did a bit of Profiling and made the quickselect and median algorithms
use the best of option for the respective input size.

Staubfinger 6b9344e86c AK: Use AK:quickselect_inline to compute AK::Statistics::median 
Quick select is an algorithm that is able to find the median
of a Vector without fully sorting it.
This replaces the old very naive implementation
for `AK::Statistics::median()` with `AK::quickselect_inline`

Staubfinger 25dd0a4d2d AK: Make Statistics::median return a mean for an even number of values 
The previous implementation of Statistics::median() was slightly
incorrect with an even number of elements since in those cases it needs
to be the arithmetic mean of the two elements that share the middle
position.

Musab Kılıç f6a43c7cf5 AK: Add min and max functions to Statistics 2021-11-06 22:09:25 -07:00
Tobias Christiansen dcf06a4f40 AK: Add Statistics helper 
This patch adds a helper to AK which allows for basic statistical
analysis of values.
The median algorithm is very naive and slow, but it works.
