This method is repeated recursively or iteratively. Here below we propose a recursive version and we leave to the interested reader the task of implementing an iterative version on his own. Insert() follows a similar approach. The candidate key for insertion is searched inside the tree. If it is found, the process returns. Otherwise if the search reaches a null node, the key is inserted in that position. The process can be either recursive or iterative. root) return NULL; return ((root->v__ < k) ?
