Scala's zip and zipWithIndex methods are useful for iterating through elements and forming pairs. ZipWithIndex pairs each element with its index, while zip combines elements from two collections.
Scala 3 has deprecated the Stream class and replaced it with the LazyList class. This update affects how methods like zip and zipWithIndex are used for pairing elements.
The zip method forms pairs by matching corresponding elements from two collections. If one collection is longer, the extra elements are disregarded, providing a way to combine elements in pairs.
