 Definition: A precise, stepbystep procedure for solving a problem or performing a task.
 Input: The data or information that the algorithm processes.
 Process: The series of operations or steps that transform the input into the desired output.
 Output: The result or solution produced by the algorithm.
 Efficiency: The measure of how well an algorithm performs in terms of time and resource usage.
Key Points
 What it is: An Algorithm is a set of steps or rules designed to solve a problem or complete a task efficiently.
 Why it matters: Algorithms are crucial for automating processes, making decisions, and analyzing data, impacting technology, business, and science.
