The final step is to optimize your code to reduce the stack usage and improve the performance of your program. There are several ways to optimize your code, such as using tail recursion ...

// and stores them in a temporary variable until the stack is empty. // 2. After the stack is empty, use `placeAtEnd` to reinsert the elements in reverse order. // 3. `placeAtEnd` recursively places ...

Java factorial recursion explained. Notice how the recursive Java factorial function does not need an iterative loop. Instead, the code repeatedly calls itself until a stop condition is met. In this ...
