Structure of a binary node: Using our binary nodes, we can construct a binary tree. In the data cell of each node, we will can store a letter. The physical representation of our tree might look something like th
Why Tree Data Structure? Other data structures such as arrays, linked list, stack, and queue are linear data structures that store data sequentially. In order to perform any operation in a linear data structure, the time complexity increases with the increase in the data size. But, it is no...

This pan-tropical invariance recasts the tropical forests of Africa from ‘odd’ in terms of species richness to statistically indistinguishable from those in Amazonia and Southeast Asia in terms of proportional patterns of abundance. Overall, using standardization by ...

To compute the height of a tree, start at its leaf nodes and assign them a height of 0. Then move up the tree using the three rules outlined to compute the height of each leaf nodes' parent. Continue in this manner until every node of the tree has been labeled. The height of the ...
