What is an Algorithm? Explain the characteristics of a good algorithm. Write an algorithm to find the largest number among three numbers. Differentiate between an Algorithm and a Flowchart.

Algorithm:

• A step-by-step procedure written in plain language or pseudocode.
• It is a textual representation of the logic.
• Focuses on the logic and sequence of operations.
• Easier to write and understand for simple problems.
• Can be difficult to visualize complex logic.

Flowchart:

• A graphical representation of an algorithm.
• Uses standardized symbols (e.g., rectangles for processes, diamonds for decisions, ovals for start/end) to depict the flow of control.
• Focuses on the visual flow and decision points.
• Easier to understand and debug complex logic visually.
• Can be time-consuming to draw for large algorithms.
