Here's how it works:
1. Start with a word.
2. Change one letter at a time to form a new word.
3. Each new word must be a valid word in the dictionary.
4. Continue until you reach your target word.
For example:
Start: CAT
Step 1: COT
Step 2: COG
Step 3: DOG
Step 4: DIG
Step 5: DUG
Step 6: DUG
End: DUG
