This problem is part of a set of problems that successively develop a more sophisticated Scrabble scoring routine. The point distribution for scoring is provided here. (Use the English points distribution.)

For this problem, you will be provided with a set of words and the accompanying bonus squares that each word covered. The words will be provided in a cell array of strings; the bonus squares will be provided in a two-level cell array of strings. Write a function to calculate the total score for the set of words using the multipliers. The multipliers are as follows:

• 'DL' = double letter
• 'DW' = double word
• 'TL' = triple letter
• 'TW' = triple word
• 'QL' = quadruple letter
• 'QW' = quadruple word

For those not familiar with QL and QW, those were introduced in Super Scrabble. Also, remember that the DL, TL, and QL multipliers take effect before the DW, TW, and QW multipliers. Also, multiple word multipliers can be present, having a cumulative effect (e.g., DW & TW = *6).

As an example, if the word were 'matlab' and the multiplier cell array was

{'','DW','','','','DL'}

then the score would be (3 + 1 + 1 + 1 + 1 + 2*3)*2 = 26. Each word in the set should be scored in this manner and the total score summed.

This is an old version of problem 4 in this series. It has been revised and is available here: Word-set multiplier scoring.
