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.
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 of each test case will be the level order traversal of the the constructed binary tree.
The task is to complete the function convert() which takes head of linked list and root of the tree as the reference.
1 <= T <= 100
1 <= N <= 103
1 <= Ki <= 103
Example(To be used only for expected output ) :
1 2 3 4 5
1 2 3 4 5
