Adds the element sep between each element of the sequence. If the sequence has less than two elements, the collection is unchanged.

Attributes

B

the element type of the returned collection

sep

the element to intersperse

Returns:

a new collection consisting of all elements of this collection interspersed with the element sep

Example:

List(1, 2, 3, 4).intersperse(0) = List(1, 0, 2, 0, 3, 0, 4)

Adds the element sep between each element of the sequence, prepending start and appending end. If the sequence has less than two elements, returns start +: this :+ end.

Attributes

B

the element type of the returned collection

end

the element to append

sep

the element to intersperse

start

the element to prepend

Returns:

a new collection consisting of all elements of this collection interspersed with the element sep, beginning with start and ending with end

Example:

    List(1, 2, 3, 4).intersperse(-1, 0, 5) => List(-1, 1, 0, 2, 0, 3, 0, 4, 5)

Produces a new sequence where all occurrences of some element are replaced by a different element.
