Normal sudoku rules apply. Each unique letter represents a unit digit from 1-9. The two-letter sandwich clue represents a two-digit number where the first letter is the tens digit and the second letter is the units digit. Clues outside the grid give the sum of the cells "sandwiched" between the 1 and 9 in the relevant row/column.
Solution code: Numbers from column 4 (top to bottom), followed by numbers from row 4 (left to right)
