Given a Linked List Representation of Complete Binary Tree. The task is to construct the Binary tree.

Note : The complete binary tree is represented as a linked list in a way where if root node is stored at position i, its left, and right children are stored at position 2*i+1, 2*i+2 respectively.
 










 


 

Input:
First line of input contains number of testcases T. For each testcase, first line of input contains length of linked list and next line contains linked list elements.

Output:
Output of each test case will be the level order traversal of the the constructed binary tree.

User Task:
The task is to complete the function convert() which takes head of linked list and root of the tree as the reference.

Constraints:
1 <= T <= 100
1 <= N <= 103
1 <= Ki <= 103

Example(To be used only for expected output ) :
Input

1
5
1 2 3 4 5

Output:
1 2 3 4 5

 

** For More Input/Output Examples Use 'Expected Output' option **
