In competitive exams, especially those involving analytical reasoning and problem-solving like AIIMS preparation, understanding algorithms and flowcharts is crucial. These tools help in breaking down complex problems into manageable steps and visualizing the logic behind solutions. This module will introduce you to the fundamental concepts of algorithms and flowcharts, equipping you with the skills to tackle a wide range of problems.

An algorithm is a step-by-step procedure or a set of rules to be followed in calculations or other problem-solving operations, especially by a computer. Think of it as a recipe for solving a problem. A good algorithm is finite, well-defined, and effective.

A flowchart is a graphical representation of an algorithm or a process. It uses different shapes to represent steps, decisions, and the flow of control. Flowcharts are incredibly useful for visualizing complex logic and making it easier to understand and debug.

In exams like AIIMS, you'll encounter questions that require logical deduction and problem-solving. Understanding algorithms helps you to systematically approach these problems, while flowcharts provide a visual aid to map out your thought process. This can be particularly useful for questions involving sequences, logic puzzles, or even understanding the underlying principles of computational thinking which are increasingly relevant.

Let's illustrate with a simple example: finding the largest of three numbers (A, B, C).

This flowchart visually represents the algorithm to find the largest of three numbers. It starts, takes inputs, makes decisions based on comparisons, and outputs the largest number before ending.
