معلم موافق رایگان بودن است.

The exam assesses computer science skills, emphasizing algorithmic thinking, data structures, and programming modifications. Topics include Big-O time complexity for sorting and searching algorithms, circular queue operations, stack-based queue reversal, and recursive subroutine design. Graph theory is explored through adjacency lists, matrix representation, and graph traversal using depth-first search. Programming tasks modify a skeleton program to validate inputs, calculate tool cards, and implement new game mechanics like blasting caps and trap cards. Tasks involve creating new classes, overriding methods, and using polymorphism. Emphasis is placed on problem-solving, object-oriented programming, and practical implementation within game-based applications.
