-/* Performance gains are grabbed through following techniques:
-
-   > hashing of needle.
-   > hashing avoids scanning of duplicate entries in needle
-     across the string.
-   > unrolling when scanning for character in string
-     across hash table.  */
-
-/* Algorithm is as below:
-   1. A empty hash table/dictionary is created comprising of
-      256 ascii character set
-   2. When hash entry is found in needle , the hash index
-      is initialized to 1
-   3. The string is scanned until end and for every character,
-      its corresponding hash index is compared.
-   4. initial length of string (count) until first hit of
-      accept needle is calculated and moved.(strspn)
-   5. The string is again scanned until end and for every character,
-      its corresponding hash index is compared.(strpbrk)
-   6. If hash index is set to 1 for the index of string,
-      set it to null and set the saveptr to point to the next char.
-   7. Otherwise count is incremented and scanning continues
-      until end of string.  */
