WebKnowing that we can assume that the right most element of a tree is also the largest element (and similarly, the left most element is the smallest). This is because there can not be anything to the right of the largest element, otherwise it wouldn't satisfy the definition of a binary search tree. WebBinary search tree is a data structure that quickly allows us to maintain a sorted list of numbers. It is called a binary tree because each tree node has a maximum of two children. It is called a search tree because it can be used to search for the presence of a …
