Such a treatment is necessarily minimal and teach neither good coding style nor advanced pro-gramming concepts. It was typeset using the LaTeX language, with most diagrams done using Tikz. Chapter 2 1-2 Problems, Introduction to Algorithms, 3rd Edition Thomas H. Cormen 2-1 Insertion sort on small arrays in merge sort Although merge sort runs in Î(nlgn) worst-case time and insertion sort runs in Î(n2) worst-case time, the constant factors in insertion sort make it faster for small n.

Understanding Introduction to Algorithms problem 1-1, How to determine the largest size n of a problem that can be solved in time t for n(lgn)? Algorithms describe the solution to a problem in terms of the data needed to represent the problem instance and the set of steps necessary to produce the intended result.
