Chapter 25.6, Problem 25.6.3CP
Explanation of Solution
“java.util.PriorityQueue” class:
This is an unbounded priority queue based on a priority heap. It does not allow null elements. In priority queue the elements are ordered according to the ordinary order.
Given statement in Listing 25.9:
- In the given statement initially create the single node tree and added to the heap.
- In every iteration, the “while” condition set the two smallest weight which are removed from the heap and are gathered to form a big tree, then the new tree is added to the heap...

So what happens if a stack resource can't be created?
Could you kindly explain the difference between the restricted and unbounded versions of the stack?
In the below stack allocation, what is the current value of top after execution of the following code (i.e. after the function using the second activation record)? Hint: remember that stacks grow from highest address toward lower address.
StackAllocatr m = new StackAllocatr(5);
m.push(1);
m.push(2);
m.pop
