Definition: In the context of computer science, "attractancy" refers to a phenomenon where an algorithm or program is able to execute efficiently and quickly on a large dataset, even if it takes longer for smaller datasets. Attraction can be achieved through various techniques such as using efficient data structures, parallel processing, or optimizing algorithms. For example, consider the following Python code: ```python def fibonacci(n): fib_sequence = [0, 1] while len(fib_sequence) < n
