How to set up patterns when using SequenceSplit
2
Given a list
lst={0,0,0,0,0,"A1",0,0,0,"B2",0,0,"C3","D4","E5",0,0,0,"F6"}
How to split it as
{{0,0,0,0,0},{"A1",0,0,0},{"B2",0,0},{"C3"},{"D4"},{"E5",0,0,0},{"F6"}}
I want to use SequenceSplit but didn't know how to set up the right pattern.
SequenceSplit[lst, {_String} -> {}]
Thanks!
