What is Seq?
A Seq in Scala represents an ordered collection of elements. Think of it like a list where the order in which you add items matters. You can access elements by their position (index), and Seq offers a variety of methods for manipulating the sequence, such as adding, removing, and searching for items. It's a fundamental data structure in Scala for working with ordered data.
