Heap Sort

A Heap is a type of data structure that is built on trees. It's a binary tree that's virtually complete. Except for the very bottom level, all levels of the tree must be filled in a heap. The last (bottom) level should be filled from left to right. The heap data structure is used for the efficient implementation of priority queues.Heap can be of two types:

Question

A function f defined on stack of integer
satisfies the following properties f(empty) =
0 and f (push (S, i)) = max (f(s), 0) + i for all
stacks S and integer i.
After pushing integers 2, -3, 2, -1, 2 in order
from bottom to top. f(s) returns the top of
the stack. What is f(s)?

Here is a method for stack operation: function (int a, int b) { if ( (a less than or equal to zero) || (b less than or equal to zero)) return 0; push (b) to stack; return function (a-1, b-1) + stack.pop; } What is the final integer value returned by function call of call (7, 7) ? Must show all the work Show all the recursive calls each time function is called. Must show all the work.
Suppose a node of a linked list is defined as follows in your program: typedef struct{ int data; struct Node* link; } Node; Write the definition of a function, printOdd(), which displays all the odd numbers of a linked list. What will be the time complexity of printOdd()? Express the time complexity in terms of Big-O notation.
How would you design a stack which, in addition to push and pop, also has a function min which returns the minimum element? Push, pop and min should all operate in O(1) time. Your design (in pseudo code) should include a class Stack and three functions, i.e., push, pop, and min.
The CopyTo method copies the contents of a stack into an array. The arraymust be of type Object since that is the data type of all stack objects. Themethod takes two arguments: an array and the starting array index to beginplacing stack elements. The elements are copied in LIFO order, as if they werepopped from the stack. write a short code fragment demonstrating a CopyTomethod call:
The ADT stack lets you peek at its top entry without removing it. For some applications of stacks, you also need to peek at the entry beneath the top entry without removing it. We will call such an operation peek2. If the stack has more than one entry, peek2 returns the second entry from the top without altering the stack. If the stack has fewer than two entries, peek2 throws an exception. Write a linked implementation of a stack class call First_Last_LinkStack.java that includes a method peek2
S and Q are integer stacks and priority queues, respectively. C mod 3 is the priority of an element C joining the priority queue Q. In other words, the elements' priority numbers are either 0 or 1 or 2. What is the output of the following code if A, B, and C are integer variables? However, the queue procedures have been modified to work on a priority queue. 1.A = 102.B = 113.C = A+B4.while (C < 110) do5. if (C mod 3) = 0 then PUSH (S,C)6. else ENQUEUE (Q,C)7. A = B8. B = C9.

Given a stack, a function is consecutive takes a stack as a parameter and thatreturns whether or not the stack contains a sequence of consecutive integersstarting from the bottom of the stack (returning true if it does, returningfalse if it does not). For example:bottom [3, 4, 5, 6, 7] topThen the call of is_consecutive(s) should return true.bottom [3, 4, 6, 7] topThen the call of is_consecutive(s) should return false.bottom [3, 2, 1] top The function should return false due to reverse order. Note: There are 2 solutions:first_is_conse cutive: it uses a single stack as auxiliary storagesecond_is_cons ecutive: it uses a single queue as auxiliary storage

Suppose you have a stack with a maximum size of 1000 elements and you want to perform the following operations: Push 500 elements onto the stack. Pop 200 elements from the stack. Push 800 elements onto the stack. Pop all remaining elements from the stack. What is the final size of the stack after performing all these operations?
