Traversal of a Binary Tree
... In this representation, there is no direct access to any node. It has to be traversed from the root to reach to a particular node. As compared to sequential representation, the memory needed per node is more. This is due to two link fields (left child and right child for binary trees) in the node. T ...

... Trees come in many shapes. Two given trees might be different from each other even though they might contain the same number of nodes. We consider the height of a tree to be given by the number of levels in the tree. We can assume that nodes in a binary tree are organised in levels, each level repr ...

... for each union, then the resulting tree structure will just be an n element linked list (and therefore it is still possible for F IND(x) to take Ω(n) time). A straight forward way to fix this pitfall is to do what is called union-by-depth. For each tree Ti , we keep track of its depth di , or the lo ...

... A basis structure consists of a spanning tree T, a set L of arcs, and a set U of arcs, such that T L U = A. For each (i,j) L, xij = 0. For each (i,j) U, xij = uij. The arc flows in T are selected so that each node satisfies its supply/demand constraint. The basis structure is feasible if the ...

B-tree
In computer science, a B-tree is a tree data structure that keeps data sorted and allows searches, sequential access, insertions, and deletions in logarithmic time. The B-tree is a generalization of a binary search tree in that a node can have more than two children (Comer 1979, p. 123). Unlike self-balancing binary search trees, the B-tree is optimized for systems that read and write large blocks of data. B-trees are a good example of a data structure for external memory. It is commonly used in databases and filesystems.
