Note that nanoseconds are usually used to calculate very short and precise program executions, such as unit testing and benchmarking.

Thus, for overall program execution, milliseconds are preferable. You need to get the time when the application starts, and compare that to the time when the application ends.

In the first article , we learned about the running time of an algorithm and how to compute the asymptotic bounds. We learned the concept of upper bound, tight bound and lower bound. In the second article , we learned the concept of best, average and worst analysis.

In the third article , we learned about the amortized analysis for some data structures. Now we are ready to use the knowledge in analyzing the real code. In this article, we learn how to estimate the running time of an algorithm looking at the source code without running the code on the computer. The estimated running time helps us to find the efficiency of the algorithm.

Knowing the efficiency of the algorithm helps in the decision making process. Even though there is no magic formula for analyzing the efficiency of an algorithm as it is largely a matter of judgment, intuition, and experience, there are some techniques that are often useful which we are going to discuss here. The approach we follow is also called a theoretical approach. In this approach, we calculate the cost running time of each individual programming construct and we combine all the costs into a bigger cost to get the overall complexity of the algorithm.
