Answer:
The new root will be 2.
<em></em>
Explanation:
The binary tree is not properly presented (See attachment)
To answer this; first, we need to order the nodes of the tree in a pre-order traversal.
We use pre-order because the question says if something is removed from the left child.
So, the nodes in pre-order form is: 14, 2, 1, 5, 4, 16.
The root of the binary tree is 14 and if 14 is removed, the next is 2.
<em>Hence, the new root will be 2.</em>
