    Anatomy of an Algorithmic Recurrence

    Anatomy of an Algorithmic Recurrence

    An algorithmic recurrence relation expresses the running time of a recursive algorithm in terms of the running time on smaller inputs.

    1. Base Case

    The time complexity for the smallest possible input size (e.g., ).

    2. Recursive Step

    Time for input , expressed as the sum of time to solve smaller subproblems and time to divide/combine.
