# Example: Measuring Time Complexity - Single loop

In this lesson, we are going to learn how to compute the running time complexity of an algorithm that involves loops.

## We'll cover the following

Let’s now calculate the running time complexity of a more complex program. We will split the code into individual operations and then compute the number of iterations.

## Simple for loop of size `n`

Here is an example of a simple loop of size * n*:
