I am trying to find a string within a string, but "anywhere", so long as it is in the right order.
but I want
ac does in fact occur interleaved as position 1 and then position 5 in
aabbc, as well as at position 2 and then position 5.
Anywhere, but in the right order. So
Is there a nice way to do this, apart from searching letter by letter, until the string is built?
