Problem Write an algorithm to find the next node (i.e., in-oder successor) of a given node in a binary search tree. You may assume that each node has a link to its parent. Solution This problem can be solved by thinking the two patterns. F…

Problem Design an algorithm and write code to find the first common ancestor of two nodes in a binary tree. Avoid storing additional nodes in a data structure. Node: This is not necessarily a binary search tree. Solution I’ll solve this pr…
