Determine if a binary tree can be converted to another by doing any number of swaps of children Construct a full binary tree from a preorder and postorder sequenceHard Find postorder traversal of a binary tree from its inorder and preorder sequence Set next pointer to the inorder successor o...
The right subtree of a node contains only nodes with keys greater than the node's key. Both the left and right subtrees must also be binary search trees. A single node tree is a BST Example An example: 2 / \ 1 4 / \ 3 5 The above binary tree is serialized as{2,1,4,#,#,3...

Tree and Graph Traversal: Recursive algorithms are commonly used for traversing tree-like or graph-like data structures, for example, recursively traversing a binary tree or finding paths in a graph. Sorting and Searching: Recursive algorithms like merge sort or binary search can be implemented in...

Such a tree structure may also provide some information on the efficiency of a recursive program by showing the depth of recursion in terms of inputs. Finally, at the end of the chapter, we consider a very important concept, namely proof by induction, which is a mathematical tool to ...
