A tree is also one of the data structures that represent hierarchical data. Suppose we want to show the employees and their positions in the hierarchical form then it can be represented as shown below: ADVERTISEMENTThe above tree shows the organization hierarchy of some company. In the above st...
For a given sequence of length n, the first number is always the root node. The rest of n - 1 nodes can be assigned to form the left and right subtree as follows. All nodes for one subtree must be consecutive in the sequence based on the preorder property. If a ...
