Bloom filter by example (see also wikipedia)

After running algorithm A on a lot of data, I end up with a large list of files like


The astute observer will note that the file for algorithm A on data 0001 and 0004 are missing.

How can I get a list of all the numbers for which A didn’t succeed?

So all together this gives the following

   ls | sed '/A/{N;d;}'  #n or N read & append next line to pattern space; 
                                          #d delete pattern space and start a new cycle 

Aother examples of Sed utilities:

 sed '$!d' file #Delete all the lines except the last one ($ is last line)
 sed '$p'  file #Print only the last line

Lines from input stream are placed into the pattern space (where they can be modified)

and then pattern space is sent to output stream. The hold buffer can be used for temporary storage.
