The method used to find a word (that is contained in a specified |
|||
dictionary) closest to a specified string of letters is: |
|||
Perform any of (three methods of actions): |
|||
::* ''delete'' any letter |
|||
::* ''insert'' any letter |
|||
:::* (any letter is inserted at any location) |
|||
:::* (this includes prefixing any letter) |
|||
:::* (this includes suffixing any letter) |
|||
::* ''substitute'' any letter at any location |
|||
<small>(Only lowercase letters were used for the [above] three methods).</small> |
|||
Perform any of the above along with any combination of any method. |
|||
This will, in effect, delete/insert/substitute any two letters: |
|||
::* ''delete'' + ''delete'' |
|||
::* ''delete'' + ''insert'' |
|||
::* ''delete'' + ''substitute'' |
|||
::* ''insert'' + ''delete'' |
|||
::* ''insert'' + ''insert'' |
|||
::* ''insert'' + ''substitute'' |
|||
::* ''substitute'' + ''delete'' |
|||
::* ''substitute'' + ''insert'' |
|||
::* ''substitute'' + ''substitute'' |
|||
No attempt was made to change (by any method) three letters or more. |
