COMPUTING PROBLEMS ON MATHEMATICAL PUZZLES OR… AN EMPIRICAL APPROACH FOR EVALUATING THE PROGRAM EXECUTION TIME

The main focus of this paper is the calculation of the program execution time. By using math puzzles as examples, it is shown how the program execution time depends primarily on the algorithm. We present three algorithms for solving the same math puzzle. F...
