There are multiple ways to design an algorithm, or considering which one to implement in an application. When thinking through this, itâ€™s crucial to consider the algorithmâ€™s **time complexity** and **space complexity**.

The time complexity of an algorithm is the amount of time taken by the algorithm to complete its process as a function of its input length, *n*. The time complexity of an algorithm is commonly expressed using *asymptotic notations*:

- Big O - $O$(n),
- Big Theta - $\Theta$(n)
- Big Omega - $\Omega$(n)
