replaces sequences of list by applying a rule or list of rules.
does only the first n replacements.
- In SequenceReplace[list,patt->lhs], patt can be an expression with head List that includes pattern constructs such as PatternSequence, Repeated (..), Blank (_) and BlankSequence (__).
- The pattern patt can also be a pattern that matches a list but does not itself have head List.
- SequenceReplace goes through a list, testing sequences that start at each successive element position. On each sequence, it tries in turn each of the transformation rules that were specified. If any of the rules apply, it replaces the sequence, then continues to go through the list, starting at the element position after the end of the sequence.
- SequenceReplace[rules][list] is equivalent to SequenceReplace[list,rules].
