An algorithm is a well-defined sequence of steps or instructions designed to perform a specific task or solve a particular problem. In computer science, algorithms are fundamental as they form the basis of programming and problem-solving. They can be simple, like sorting a list of numbers, or complex, like training a machine learning model.
Key Characteristics of Algorithms
Clear and Unambiguous: Each step in an algorithm must be precisely defined and lead to only one interpretation.
Well-Defined Inputs and Outputs: An algorithm should have clearly defined inputs and produce well-defined outputs.
Finite: An algorithm must terminate after a finite number of steps.
Feasible: The steps of an algorithm should be practical and executable with the available resources.
Language Independent: An algorithm should be implementable in any programming language.

An accompanying notion is the design of a particular data structure that enables an algorithm to run efficiently. The importance of data structures stems from the fact that the main memory of a computer (where the data is stored) is linear, consisting of a sequence of memory cells that are serially numbere… - Although data items are stored consecutively in memory, they may be linked together by pointers (esse…
Pointers also provide the ability to implement more complex data structures. A graph, for example, is a set of nodes (items) and links (known as edges) that connect pairs of items. Such a graph might represent a set of cities and the highways joining them, the layout of circuit elements and connecting w…
