Hi Ron Rosenfeld,
Thank you very much for your help.
Could I use your first function as a VBA code?
In this second case, is is possible that we have a typo. In this case
speak about 1 lost cut means that you will cut the sequence only after
the first K appear, never to the first one. But you will have
intermediates in such process because you never now where will be
performed the first cut.
