Algorithms
What are data they?
Algorithm is a finite sequence of executable actions that aim to obtain the resolution of a task. An algorithm does not necessarily represent a computer program, but the steps needed to perform a task. It does not answer the question “what to do?”, but rather “how to do it“ [1].
To perform a task, the algortithm must be unambiguous, standardized and precise. In other words a logical, finite and defined sequence of instructions that must be followed.
Algortithms can repeat steps or make decisions until the task is completed. Its implementation can be done by a computer, by another type of automaton or even by a human being.
Different algorithms can accomplish the same task using a different set of instructions in more or less time, space, or effort than others. This difference may be a reflection of the applied computational complexity, which depends on data structures suitable for the algorithm.
Here we are going to talk about the main basics. I will explain it in detail and with a practical approach, where I will be implementing some data structure and understanding the computational complexity, so that we can better understand how they work.
