Solution
The statement "Recursion uses more memory compared to iteration" is true.
Here's why:
-
In recursion, each recursive call creates a new layer on the system stack, which requires additional memory. This is because each recursive call has to remember its state (including any variables) so it can resume where it left off when the recursive call it made returns.
-
In iteration, the state is usually kept in a set of variables, and the loop is repeated until a certain condition is met. This does not require additional memory for each iteration.
Therefore, recursion generally uses more memory compared to iteration.
