Recursion practice

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

- 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.

- Write the code to perform BST deletion

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

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

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

intdoit(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 << p->data << endl;

} }
