/**
* A set of collection libraries suited for small data sets which are also optimized for Android,
* usually by sacrificing performance for efficiency in memory.
* <ul>
* <li>
* <b>{@link androidx.collection.ArraySet} / {@link androidx.collection.ArrayMap}</b>
* <p>
* Implementations of {@link java.util.Set} and {@link java.util.Map}, respectively, which
* are backed by an array with lookups done by a binary search.
* </li>
* <li>
* <b>{@link androidx.collection.SparseArrayCompat} /
* {@link androidx.collection.LongSparseArray}</b>
* <p>
* Map-like structures whose keys are {@code int} and {@code long}, respectively, which
* prevents boxing compared to a traditional {@link java.util.Map}.
* </li>
* <li>
* <b>{@link androidx.collection.LruCache}</b>
* <p>
* A map-like cache which keeps frequently-used entries and automatically evicts others.
* </li>
* <li>
* <b>{@link androidx.collection.CircularArray} /
* {@link androidx.collection.CircularIntArray}</b>
* <p>
* List-like structures which can efficiently prepend and append elements.
* </li>
* </ul>
