Study Notes

Algorithms

  • An algorithm is a process or set of rules for calculations or problem-solving.
  • It's a set of instructions defining how a task is executed to get a desired outcome.
  • A cooking recipe provides a good analogy. Following step-by-step instructions yields the desired dish.
  • Similarly, algorithms in programming guide the steps to achieve the expected output.

Pseudocode

  • Pseudocode is a simplified way to write programming code using English-like phrases.
  • It's not an actual programming language.
  • It helps create program logic before writing the code in a specific programming language.
