Study Notes

Algorithms

A step-by-step set of instructions aimed at solving a problem or completing a task.
Resembles a recipe, guiding the user through specific steps needed to achieve a goal.
Comprised of clear, specific actions that must be followed in a defined sequence.
Requires input (akin to ingredients) which leads to an output (the final result or solution).
Concludes with an outcome or a solution to the problem being addressed.
Example algorithm for finding the largest number in a list:
- Start with the first number as the initial largest.
- Compare it with subsequent numbers in the list.
- Update the largest if a larger number is found.
- Continue until all numbers have been compared.

Flowcharts

Visual representation of an algorithm, simplifying understanding through diagrams.
Utilizes various shapes to denote different types of actions:
- Oval represents the Start and End points.
- Rectangle signifies a process or instruction.
- Diamond indicates decision points involving yes/no questions.
- Arrows depict the flow direction between steps.
Example flowchart for finding the largest number includes:
- Start with an Oval shape, initializing the largest number in a Rectangle.
- Decision point to check if more numbers exist (Diamond).
  - If yes, proceed to compare (next step in Diamond).
  - If no, move to End (Oval).
- Comparison process follows with updating as necessary, looping back as required until the conclusion is reached.

Importance of Algorithms and Flowcharts

Enhance clarity by outlining steps clearly and visually representing processes.
Facilitate problem-solving by breaking down complex issues into smaller, manageable components.
Improve communication by allowing individuals to present their solutions in an accessible manner.
