FilledSmallSquare Split[list] splits list into sublists consisting of runs of identical elements.

FilledSmallSquare Split[list, test] treats pairs of adjacent elements as identical whenever applying the function test to them yields True.

FilledSmallSquare Example: Split[a, a, b, b, a, a, b] LongRightArrow.

FilledSmallSquare The default function used to test whether elements are identical is SameQ.

FilledSmallSquare Split can be used to perform run-length encoding.

FilledSmallSquare See Section 1.8.10 and Section 2.4.4.
