Split

Split[list]
splits list into sublists consisting of runs of identical elements.
Split
treats pairs of adjacent elements as identical whenever applying the function test to them yields True.
MORE INFORMATION
  • The default function used to test whether elements are identical is SameQ.
  • Split can be used to perform run-length encoding. »
