Loopless algorithm

The concept of a "Loopless algorithm" typically refers to an approach in algorithm design that avoids traditional looping constructs—like `for` or `while` loops—in favor of alternative methods. This can be implemented for various reasons, including improving performance, simplifying reasoning about code, or adhering to certain programming paradigms, such as functional programming. One common example of a loopless approach is the use of recursion to achieve iteration.
