The search time for a balanced binary search tree is Log_2N N^2 N N^2-N If a statement appears below the recursive call The statement is executed on the way "out of the recursion." The statement is executed only once. The statement is executed on the way "into the recursion." The statement is never executed. With each recursive call something is pushed onto the runtime stack.
