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.
Optional extras:
Null insertions (empty strings) are not allowed.
A bounded capacity can be specified, so there is an upper limit to the number of items contained, with the least recently added items dropped on overflow.
See a video tutorial showing how to solve this kata in Python.
More tests:
While getting items by index, supplied index-value should be within the bounds of List [eg. if maximum item counts of list is 5 then supplied index is less than 4 as index starts from 0 (zero)] Negative index value not allowed [>0] Size limit is must if not supplied make 5 as default [0-4] List can be non-sizable means without upper limit list can be created [Hint-try property or constructor initializers]
