- O(n^2) - quadratic time
Understanding these can help developers make better choices while coding.
Mathematical Induction and Recursion
Mathematical induction is a method of proof that is essential in computer science for establishing the correctness of algorithms. It consists of two parts: the base case and the inductive step. The base case verifies that the statement holds for the initial value, while the inductive step demonstrates that if it holds for an arbitrary case, it holds for the next. This often parallels recursive algorithms where the solution to a problem depends on the solution to smaller instances of the same problem.
Recursion is a programming technique where a function calls itself to solve smaller instances of the same problem. This method can lead to elegant solutions, particularly for tasks like tree traversal or sorting. However, care must be taken to avoid excessive memory use or infinite loops by ensuring that the recursive calls ultimately lead to a base case.
A well-designed algorithm not only performs well but also remains comprehensible and maintainable.
