Populate a tree via a text file (input.txt) Make sure that after every insert, the tree is balanced.
At the end, display the tree in level format. Make sure to include the height and the balance
factor of every node in your output. Redirect the display to an output file (output.txt)
Hint:
//I will not accept any other
//This is not a recursive algorithm
node * rebalance(node *node){
node->height = max(height(node->left), height(node->right)) + 1;
int balance = getBalance(node); //node->left - node->right
/*do rotations as necessary
If Left heavy outside : return rightRotate(node);
If right heavy outside: return leftRotate(node);
If left heavy inside: left rotation first, right rotation 2nd, return top node
node->left = leftRotate(node->left);
return rightRotate(node);
if right heavy inside: right rotation first, left rotation 2nd, return top node
node->right = rightRotate(node->right);
return leftRotate(node);
if no rotation, return node

//non-tail recursive algorithm because of rebalance
