+changes:
+Base Case Check: In your searchWord function, you should check if index is equal to len(word) - 1, but also need to ensure that the character at index matches the character at the current position before returning true. You should adjust this condition to account for reaching the end of the word correctly.
+
+Visited Check: You should also ensure that the last character in the word is checked correctly.

 }
+Key Changes:
+Base Case Update: The base case now checks if index is equal to len(word), indicating a full match of the word.
+Boundary and Match Check: The conditions in searchWord ensure the current cell is valid, not visited, and matches the corresponding character in the word before proceeding.
+Backtracking Logic: The backtracking logic is preserved but placed correctly to ensure valid states.
