Mar 30, 2009 a binary tree embodies a finite set of data items that is either empty or partitioned into three disjoint subsets. Afterwards, whenever an element is to be inserted, first locate its proper location. It implies that we organize the data so that items of information are related by the branches. Trees are used to represent data containing a hierarchical relationship between elements e.
