The JSON data is already "ordered", means that an entry will have above itself a parent node or brother node, and under itself a child node or a brother node. This is binary tree. Then we traverse the given parent array and build the tree by setting parent-child relationship defined by (A[i], i) for every index i in the array A. all nodes have left and right children except for the leafs. Following is a simple algorithm where we first find the middle node of list and make it root of the tree to be constructed. Easy. I am trying to create a tree out of this array.
