Analyze the memory needs for stacks and queues

2. Compute the memory needs for a fixed capacity queue of Rectangles with a capacity of 20
4. Compute the memory needs for a dynamic capacity stack of Doubles with the initial capacity of 10, in which we performed the following operations: push 17 elements, pop 5, push 30 elements.
6. Compute the memory needs for a linked list queue of Booleans in which we performed the following operations: enqueue 5 elements, dequeue 2 elements, enqueue 7 elements.
