Scala Lists are quite similar to arrays which means, all the elements of a list have the same type but there are two important differences. Create a Regex object by invoking the .r method on a String, and then use that pattern with findFirstIn when you’re looking for one match, and findAllInwhen looking for all matches. Then the problem shows two data types, namely List and Int, but it does not state that the list has to contain integers. The scala package contains core types like Int, Float, Array or Option which are accessible in all Scala compilation units without explicit qualification or imports.. It computes a lazy list that contains a Fibonacci sequence starting with the given two numbers. The type of a list that has elements of type T is written as List[T]. Adds an element x at the beginning of the list, def addString(b: StringBuilder): StringBuilder. Checks for calls of .apply(idx) on a Seq where the index is not a literal and the Seq is not an IndexedSeq. Computes the multiset intersection between the list and another sequence. The head of a cell contains a list element. Appends all elements of the list to a string builder using a separator string.
