haplesshero13/RecentlyUsedList-Kotlin

A Kotlin project for the RecentlyUsedList kata

Recently Used List

Develop a recently-used-list class to hold strings uniquely in Last-In-First-Out order.

• The most recently added item is first, the least recently added item is last.
• Items can be looked up by index, which counts from zero.
• Items in the list are unique, so duplicate insertions are moved rather than added.
• A recently-used-list is initially empty.
• The Recently Used List reports size equal to the number of items in the list.
