Bounded Stack vs Unbounded Stack: What's the Difference?

What data value does a bounded stack data structure require that an unbounded stack data structure does not?

A. AllocationSize

B. Array Length

C. MaxLength

D. The data value that a bounded stack requires, which an unbounded stack does not, is the "maxlength" that limits the size of the stack.

Answer:

The data value that a bounded stack requires, which an unbounded stack does not, is the "maxlength" that limits the size of the stack.

A bounded stack data structure requires a data value called "maxlength" that an unbounded stack data structure does not require. The "maxlength" refers to the maximum number of elements that can be stored in the bounded stack. It defines a limit on the size of the stack, and once this limit is reached, no more elements can be added.

For example, let's say we have a bounded stack with a "maxlength" of 5. We can push 5 elements onto the stack, but if we try to push a 6th element, it will be rejected because it exceeds the maximum length.

On the other hand, an unbounded stack does not have a maximum limit on the number of elements it can store. It can grow dynamically as needed, allowing for an indefinite number of elements to be added.
