Given the needle: 

00001010 01010100 00011010
The bad shift table for handling eight bits at a time: 
00001010                        needle offset 0
 0001010 0                      needle offset 1
  001010 01                     needle offset 2
   01010 010                    needle offset 3
    1010 0101                   needle offset 4
     010 01010                  needle offset 5
      10 010101                 needle offset 6
       0 0101010                needle offset 7
         01010100               needle offset 8
          1010100 0             needle offset 9
           010100 00            needle offset 10
            10100 000           needle offset 11
             0100 0001          needle offset 12
              100 00011         needle offset 13
               00 000110        needle offset 14
                0 0001101       needle offset 15
                  00011010      needle offset 16
The shift follows from needle offset. If some 8-bit value repeats, the smallest shift is used.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":
