During union by size method, which data structure is used to improve the balancing of tree?
Select correct option:
Array
Stack
Linked List
Tree
1.
The main reason of using heap in priority queue is
improve performance
code is readable
less code
heap can't be used in priority queues
2.
We implement the heap by ____________
Threaded Tree
AVL tree
Complete binary tree
Expression
3.
A simple sorting algorithm like selection sort or bubble sort has a worst-case of
O(1) time because all lists take the same amount of time to sort
O(n) time because it has to perform n swaps to order the list.
O(n2) time because sorting 1 element takes O(n) time - After 1 pass through the list,
either of these algorithms can guarantee that 1 element is sorted.
O(n3) time, because the worst case has really random input which takes longer to.
4.

5
25
35
50
5.
Which one of the following is NOT true regarding the skip list?
Each list Si contains the special keys + infinity and - infinity.
List S0 contains the keys of S in non-decreasing order.
Each list is a subsequence of the previous one.
List Sh contains only the n special keys.
6.
Which of the following is not true regarding the maze generation?
Randomly remove walls until the entrance and exit cells are in the same set.
Removing a wall is the same as doing a union operation.
Remove a randomly chosen wall if the cells it separates are already in the same set.
Do not remove a randomly chosen wall if the cells it separates are already in the same set.
7.

Expression
10.
Which of the following statement concerning heaps is NOT true?
Traversing a heap in order provides access to the data in numeric or alphabetical order.
Removing the item at the top provides immediate access to the key value with highest (or lowest) priority.
Inserting an item is always done at the end of the array, but requires maintaining the heap property.
A heap may be stored in an array.
