Provides uniform APIs for accessing its first and last elements, and for processing its elements in reverse order. Value: Improves developer productivity by offering a uniform set of operations that apply across a collection type that represents a sequence of elements with a defined encounter order...
There’s also a new method called reversed that returns a SequencedCollection that is a view on the underlying collection but in reverse order, which makes it super easy to iterate or stream over the collection. Copy code snippet Copied to Clipboard ...

We will list the files in a directory, read the lines, and count the number of wtf strings. This way we automate the code review process quality measurement (joking). It is said that the code quality is reverse proportional to the number of the WTFs during the code review. The solution...
