KEYSTROKES: TASK DESCRIPTION
Deadline May 31, 2005
I am not a good typist. When I was creating this
POTM I typed in
when I meant to type
THE SHORT PROBLEM STATEMENT
To correct the error, I could delete
all the letters and type in the correct spelling.
Or I could move to the second position
and delete the "YE" and then add "EY" and
then move to the next-to-last position and then add the "E".
But surely YOU can write a program figure out the most
efficient way to perform this sort of operation.
You will be given two blocks of text, a "starting" block and a
"target" block. Your program, using special POTM "editor-like" operations
defined in the problem statement details,
will be asked to provide a sequence of editing operations
and typed letters
that will transform the initial block to the target block.
Short sequences are good! I'm hoping the problem
turns out to be more difficult than it sounds!
Check here for all the details!
