Final answer:
To solve the issue of high memory usage when the stack becomes too tall, you can use tail recursion or recursion elimination. This involves transforming a recursive function into a tail-recursive one, which avoids storing multiple function calls on the stack. Alternatively, you can use iteration instead of recursion to perform the necessary calculations.
Step-by-step explanation:
When the stack becomes too tall and consumes a lot of memory, one way to solve it is through a technique called recursion elimination or tail recursion.
Recursion refers to a function calling itself, which results in multiple function calls being stored on the stack. Tail recursion, on the other hand, is a form of recursion where the recursive call is the last operation performed in a function. This allows the compiler to optimize the code and avoid storing information for every function call on the stack.
By transforming a recursive function into a tail-recursive one, you can reduce the memory usage and prevent stack overflow. One way to achieve this is by using iteration instead of recursion. Instead of calling the function recursively, you can use a loop to perform the necessary calculations and update the variables. This way, you avoid storing multiple function calls on the stack and reduce the memory usage.
