[Jprogramming] A Different Less?

[June Kim (김창준)]

Hello

I am looking for a verb(cless) that does something similar to Less(-.) but
counting the elimination, for example:

   'abcabbe' -. 'abbe'

c

   'abcabbe' cless 'babe'  NB. get rid of y letters counting the occurrences

'cab'


It is easier to define such a verb recursively: 'abcabbe' cless 'babe'
equald to 'e' cless~ 'b' cless~ 'a' cless~ 'b' cless~ 'abcabbe'


I think recursive definition isn't a usual J-ic approach.


How would you implement such a verb elegantly(with which I mean short)?
