It can also be used for finding the shortest paths from a single node to a single destination node by stopping the algorithm once the shortest path to the destination node has been determined. Its time complexity is O(E + VlogV), where E is the number of edges and V is the number of vertices.

• Given a sorted array keys[0.. n-1] of search keys and an array freq[0.. n-1] of frequency counts, where freq[i] is the number of searches to keys[i].Construct a binary search tree of all keys such that the total cost of all the searches is as small as possible. Let us first define the cost of a BST.

trees, which requires linear space and can answer queries in O(log ‘ n) time. Combining with van Emde Boas’ data struc-ture, they got a search time of O(min{lg n lg ‘, lg‘}), which is always O(√ lgn). In 1999, Beame and Fich  found an improvement to van Emde Boas’ data structure bringing the search time down to O(lg ‘ lg lg ‘

Full v.s. Complete Binary Trees. According to wikipedia. A full binary tree (sometimes proper binary tree or 2-tree) is a tree in which every node other than the leaves has two children. A complete binary tree is a binary tree in which every level, except possibly the last, is completely filled, and all nodes are as far left as possible.

Mar 27, 2014 · Tree balancing Tree balancing is important for uses which perform spatial classification of points, lines, and surfaces. This includes ray tracing and solid modelling. Tree balancing is important for these applications because the time complexity for classification is based on the depth of the tree.

Binary search can be performed on a sorted array. In this approach, the index of an element x is determined if the element belongs to the list of elements. If the array is unsorted, linear search is used to determine the position.

The optimal binary search tree problem when the PI’s are all zero is called the op- timal alphabetic tree problem. An 0(n2) time, O(n*) space algorithm for constructing optimal alphabetic trees was first proposed by Hu and Tucker. This was later im- proved by Knuth.

Therefore, time complexity of binary search algorithm is O(log 2 n) which is very efficient. Auxiliary space used by it is O(1) for iterative implementation and O(log 2 n) for recursive implementation due to call stack. Avoid Integer Overflow: signed int in C/C++ takes up 4 bytes of storage i.e.

Answer: Option 'C' The property of a binary search tree is that the lesser elements are to the left and greater elements are to the right, we use this property here and iterate through the tree such that we reach a point where the 2 elements are on 2 different sides of the node, this becomes the least common ancestor of the 2 given elements.
It can also be used for finding the shortest paths from a single node to a single destination node by stopping the algorithm once the shortest path to the destination node has been determined. Its time complexity is O(E + VlogV), where E is the number of edges and V is the number of vertices.
