Study Notes

Algorithm Definition

  • An algorithm is a process or set of rules for calculations or problem-solving.
  • It's a set of instructions for completing a task to get a specific outcome.

Algorithm Example

  • Cooking a recipe is similar to an algorithm.
  • Instructions are followed sequentially to achieve the desired result (cooked dish).
  • Algorithms in programming also achieve desired output step-by-step.

Pseudocode Explanation

  • Pseudocode is an English-like representation of programming code.
  • It's not a real programming language.
  • It uses short phrases to outline program logic before creating the actual code.
