Compute the depth of a node v in tree T: int depth(T, v) Algorithm: int depth(T,v) {if T.isRoot(v) return 0 return 1 + depth(T, T.parent(v))} Analysis: • O(number of ancestors) = O(depth_v) • in the worst case the path is a linked-list and v is the leaf • ==> O(n), where n is the number of nodes in the tree Algorithms on trees: Depth
Tree structures are indeed a breakthrough in data organization, for they allow us to implement a host of algorithms much faster than when using linear data structures, such as array-based lists or linked lists.

22 Οκτ 2024 · Learn the fundamentals of Tree Data Structure: its representation, importance, types, operations, implementation, applications, advantages and disadvantages
We could use Python lists to implement binary trees. For example: We could also use a flat (one-dimensional list). ... Choosing a specific data structure has consequences on which operations can be performed faster. Test: Is this a BST? Start at the root and compare the new data value with the root. If it is less, move down left.
cbna CS213/293 Data Structure and Algorithms 2023 Instructor: Ashutosh Gupta IITB India 16 Binary tree Definition 6.13 An ordered tree T is abinary treeif |children(n)|≤2 for each n ∈T. We define the left and right child ofn as follows. if chidren(n) = [n 1,n 2], left(n)= n 1 and right(n)= n 2. If chidren(n) = [n 1], n
