Trees and backtracking are important topics in data structures.

In theoretical computer science and mathematics, the theory of computation is the branch that deals with how efficiently problems can be solved on a model of computation, using an algorithm.Trees and backtracking are important topics in this subject.

Physics is the natural science that studies matter and its motion and behavior through space and time and that studies the related entities of energy and force.

Computer Organisation Architecture is very important in computer science engineering. In computer engineering, computer architecture is a set of rules and methods that describe the functionality, organization, and implementation of computer systems
