Aaaa nbbbb n n split n 0 aaaa 1 n 2 bbbb 3 n 4 5 n we don t see that used very often but it can be useful.

Whenever the pattern matches a zero length string str is split into individual characters. It can cut up a string into pieces along a pre defined string or regex returning an array of smaller strings. It is similar to the split function of perl. Share a link to this answer.
