The following questions are based on information from the book “Introduction to Algorithms” by Thomas H. Cormen et al.
Q: What is an algorithm (p.5) ?
A: An algorithm is a well-defined computational procedure that takes input and output. In other words, it is a sequence of computational steps that transforms the input into the output.
Q: Give a few examples of real-life usage of algorithms (p.6-8).
