Exercise (p. 605)
11.1, 11.2, 11.7, 11.9

1) Write a code segment that does the following:

1. Defines constants MAX_ROWS equal 25 and MAX_COLUMS equal to 10
2. Defines a two-dimensional boolean array data with 25 rows, where each row consists of 10 elements.
3. Initializes array data so that elements whose row subscript values are odd have the value true and initializes the other elements to false

2) Assume that you are creating a class Crossword which stores a crossword puzzle as a two dimensional array of characters. The Crossword class has the data field:
private char[][] puzzle;
which is allocated in the constructor and assigned letters. You will write two methods for this class.

• isDownAtPosition(String word, int row, int column) - This method determines if the word matches the letters in the puzzle traversing down the column starting at the position row, column. The method returns true or false.
• isDownWord(String word) - This method searches the puzzle to determine if the word occurs in the down direction in the puzzle. It should also return true or false.
