Answer:

22

Explanation:

1. We are going to have at hand 32 Enqueue Operation, with 10 from front and 15 dequeue and 5 empty queue operation

2. You dequeued total number of 15-5 =10 elements since 5 dequeue did not change the state of the queue, so invariably 10 dequeue is done.

3. Next is to enqueued a total of 32 elements.

Enqueue Operation do not change the state(and Size) of the queue, and can be ignored.

4. To arrive at the Total Size of queue, we will have 32-10 = 22 at the end

Answer : 22 because its a 5 dequeue Operations.

Which statement best describes one reason why assembly language is easier
viktelen [127]

Answer:

machine language uses binary code and assembly language uses mnemonic codes to write a program.

Explanation:

In a nutshell, machine language uses binary code, which is almost impossible for humans to decipher, whereas assembly language uses mnemonic codes to write a program. Mnemonic codes make it simpler for humans to understand or remember something, and so make the language a bit easier for humans to use than machine code.

Zina [86]

Answer:

Option B is the correct answer for the above question.

The control structure is a decision type structure which can be either true or false. It has two options-- If this then, does this otherwise do this. When the user wants to write he control structure then he can do this by the help of the following syntax in python language--

if(condition):

do this

else:

do this

The above question wants to ask about the concept which is used in the programming for a decision then the answer is control structure which is referred from the option B. Hence B is the correct option while the other is not because--

  • Option A states about the flowchart which is the picture form of the instruction.
  • Option C states about the pseudocode which is the language form of the instruction.
  • The operator is also not the correct option because it is used to perform the operation.

Nesterboy [21]

A data structure called a binary search tree makes it simple to keep track of a sorted list of numbers.

<h3>What is a binary search tree?</h3>

A binary search tree, also known as an ordered binary tree or a sorted binary tree in computer science, is a rooted binary tree data structure where each internal node's key is higher than all the keys in its left subtree and less than all the keys in its right subtree.

A data structure called a binary search tree makes it simple to keep track of a sorted list of numbers. Because each tree node has a maximum of two offspring, it is known as a binary tree. It can be used to search for the presence of a number in O(log(n)) time.

A binary search tree (BST) is a specific type of binary tree in which every node has a comparable key and a connected or associated value.
