A Binary search tree (referred to as BST hereafter) is a type of binary tree. It can also be defined as a node-based binary tree. BST is also referred to as ‘Ordered Binary Tree’. In BST, all the nodes in the left subtree have values that are less than the value of the root ...
Let us assume that the vertices of the triangulation \(\mathcal {T}\) are stored in an array as they are found the first time when the left-to-right depth-first-search traversal of the PS-tree is performed. In the triangulation of Fig. 1, the ordered sequence of vertices stored in ...
looking for the particular node. There's no direct access to a given node as with an array. Searching a binary tree can take linear time, as potentially all nodes will need to be examined. That is, as the number of nodes in the binary tree increases, the number of steps to find an...

Then the implementation could look like this: ...// a sorted array is stored as a[0], a[1], ..., a[n-1]intl=-1,r=n;while(r-l>1){intm=(l+r)/2;if(k<a[m]){r=m;// a[l] <= k < a[m] <= a[r]}else{l=m;// a[l] <= a[m] <= k < a[r]}} ...
Draw a tree that starts from a single node (the root node) and has a maximum of two possible branches at each node. One of these branches corresponds to a 1 and the other branch corresponds to a 0. In this book, we will adopt the convention that when we draw a tree with the root...
