What is Range?
A Range in Scala represents an ordered sequence of integers (or other numeric types) with a consistent step size. You define a range by specifying its start, end (inclusive or exclusive), and the increment between elements. Ranges are memory-efficient because they don't store all the numbers; instead, they calculate each element on demand, making them ideal for iterating over large sequences or generating arithmetic progressions without the overhead of storing every single value.
