Recursive Functions
Explore the concept of recursive functions in Dart, where functions call themselves to solve problems like calculating factorials. Understand how recursion breaks down tasks into smaller expressions, the role of base cases, and how Dart executes recursive calls. This lesson helps you grasp recursion to apply it effectively in Dart programming.
We'll cover the following...
Recursive functions are functions that call themselves in their own function body. This may seem a bit strange right now, but let’s see how this works.
Recursion
Recursion is the process of breaking down an expression into smaller and smaller expressions until you’re able to use the same algorithm to solve each expression. The smaller expressions are similar versions of the original expression.
One way to implement recursive functions is by using an if-else statement. The if represents the base case which is the smallest possible expression on which an algorithm will run and the else represents the recursive call; when a ...
