## Question 1
What is the serialized output of this tree using level order traversal?
```
          __ 350 
	     |
	  __ 75 ______ 
	 |            |
	 25 _     ___ 200 
	     |   |
	     50  100
```

### Options

1. [350, 75, 25, 50, 200, 100]
Incorrect

----------------------------

2. [350, 75, 25, 200, 50, 100]
Correct
Level-order traversal of the binary tree. 
----------------------------

3. [25, 50, 75, 100, 200, 350]
Incorrect

----------------------------

4. [50, 25, 100, 200, 75, 350]
Incorrect

----------------------------

## Question 2
What is the expected output of deserialization of the list generated from the preorder traversal of a tree?

 [5, 2, 1, 4, 23, 13, 10, 25]
### Options

1. ```
          __ 23 __
	     |        |

   _ 2 _    _ 13    
  |	    |  |
  1	    4  10
```
Incorrect

----------------------------

2. ```
          __ 10 __
	     |        |
	  __ 5     __ 23 __
	 |        |        |
   _ 2 _      13       25
  |	    | 
  1	    4  
```
