WebJan 17, 2024 · Explanation: Recursive function (reverse) takes string pointer (str) as input and calls itself with next location to passed pointer (str+1). Recursion continues this way when the pointer reaches ‘\0’, all functions accumulated in stack print char at passed location (str) and return one by one. WebGiven a binary tree, write an iterative and recursive solution to traverse the tree using inorder traversal in C++, Java, and Python.
