2.3. Design Patterns 2.3.1 Strategy Have a chessManager class that has both chessboard and strategy. Provide the strategy on the current board setting to the chess manager, and it takes care of implementing the strategy on chessboard. Pseudo-code: public class ChessManager { Chessboard board; Strategy movePicker; // other members makeMove() { Move = movePicker.suggest(board); . . . } // other methods ChessManager(Strategy s) { movePicker = s; } }

2.3.2. composite The composite pattern would work best for this music program because the program breaks a song down into subgroups with a hierarchical design. A song is created from verses, which are made up of melodies, which are made up of notes. The user can do whatever is needed with each group of notes, melodies, or verses to compose a song. Pseudo-code: //a song is made of verses, each with subgroups of melodies, each //with a subgroup of notes public class Verse { int verse_number; //verse id number string melody; //melody is string of notes

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
