Recursion practice

Problem 0 Using recursion (and no arrays), write the code to read in a series of numbers (until EOF) and then print them backwards.

Problem 1 Write is leftist which determines if every node in a tree has a right child which is never of greater height that the left child. a a b c d e a b c d e Leftist

Problem 2 Write the code to perform BST deletion

Problem 3 Write the code to insert a node into a binary search tree that has parent pointers.

Problem 4 Find the largest element value in a binary tree (which is not a BST)

Problem 5 Write the pseudo code to list all possible rearrangements of the letters of a provided word. void printAnagrams(string prefix, string word)

Reading recursion int doit(int x) { if (x == 0) return 0; else { cout << x; return doit(x - 1); }

int doit2(int x, int y) { if y==0 return 1; return (x * doit2(x, y – 1)); }

void doit3(tree_node *p) { if (p != NULL) { doit3(p->left); doit3(p->right); cout data << endl; }
