The statement "Recursion uses more memory compared to iteration" is true. This is because every time a recursive call is made, the computer needs to "remember" the previous state of the function. This information is stored in a stack, which uses up memory. On the other hand, iteration doesn't require the computer to remember previous states, so it generally uses less memory.

The statement "Recursion uses more memory compared to iteration" is true.

Here's why:

1. In recursion, each recursive call creates a new layer of the function on the stack, which requires additional memory. This is because each recursive call has to remember its state (i.e., local variables, return address, etc.) until the base case is reached and the function starts returning.

2. In iteration, the state is usually determined by a set of variables, and these variables get updated within each iteration. The memory requirement is constant and does not increase with the number of iterations.

Therefore, recursion uses more memory compared to iteration. However, whether recursion or iteration is better depends on the specific problem and the specific circumstances. Neither is always better or simpler than the other.
