    Study Notes

    Algorithm Basics

    • An algorithm is a clearly specified set of simple instructions to solve a problem.
    • It takes a set of values as input and produces a value or set of values as output.
    • Algorithms can be specified in English, as a computer program, or as pseudo-code.

    Problem and Algorithm

    • A problem can be a real-world problem or an instance from a real-world problem that requires a program or set of instructions.
    • An algorithm is designed for a problem and is a step-by-step procedure.

    Input, Processing, and Output

    • After designing an algorithm, the required and desired inputs are provided to the algorithm.
    • The input is given to the processing unit, which produces the desired output.

    Why We Need Algorithms

    • Algorithms are necessary for scalability and performance.
    • Scalability helps break down big real-world problems into smaller, manageable steps.
    • Performance is improved when problems can be easily broken down into smaller steps.

    Characteristics of an Algorithm

    Finiteness

    • An algorithm must complete after a finite number of steps.
    • The algorithm should have a finite number of steps.
    • Examples of finite steps include specified instructions, whereas infinite steps are represented by infinite loops.

    Data Structures and Programs

    • A data structure is the way data are organized in a computer’s memory.
    • A program is a set of instructions written to solve a problem, which includes data structures and algorithms.
    • Program = Data structures + Algorithm.
