How does asymptotic analysis contribute to our understanding of algorithm efficiency?
Asymptotic analysis provides a framework for evaluating how algorithms perform as the size of the input increases. By focusing on the leading terms and their growth rates, it allows us to classify algorithms based on their efficiency using notations like Big O.
