An algorithm is a systematic, step-by-step procedure used to solve a problem or perform a specific task. It consists of a finite sequence of well-defined instructions that take input values, process them through a series of operations, and produce an output. Algorithms are fundamental in computer science and mathematics, enabling automation and efficient problem-solving in various fields, such as data processing, artificial intelligence, and cryptography.
Algorithms must be precise, unambiguous, and efficient, ensuring they operate within a reasonable time frame and resource usage. They can be expressed in different forms, including natural language, flowcharts, or programming code. The effectiveness of an algorithm is measured based on factors such as correctness, speed (time complexity), and resource efficiency (space complexity). Whether simple or complex, algorithms drive modern computing and digital systems.
How Algorithms Work:
-
Input: The algorithm takes one or more inputs, such as numbers, text, or data from a database.
-
Processing: It follows a set of predefined rules or operations, such as calculations, comparisons, or logical decisions.
-
Decision Making (if applicable): Some algorithms include conditions that determine different execution paths based on the input.
-
Iteration (if needed): Repeating steps (loops) may be necessary until a condition is met.
-
Output: The final result is generated, which could be a number, sorted data, a decision, or any computed value.
