Let's say I have the word "CAT". These words differ from "CAT" by one letter (not the full list)
- CUT
- CAP
- PAT
- FAT
- COT
- etc.
Is there an elegant way to generate this? Obviously, one way to do it is through brute force.
pseduo code:
while (0 to length of word)
while (A to Z)
replace one letter at a time, and check if the resulting word is a valid word
If I had a 10 letter word, the loop would run 26 * 10 = 260 times.
Is there a better, elegant way to do this?
