Search In Vain Two kinds of rotates in this world To the left, and right And in an RB search tree They preserve black height. So I search in vain Like I always do I can insert love But I can't delete you Two kinds of rotates in this world To the right, and left And when they're splayin' a node They halve that node's depth So I search in vain Like I always do I can insert love But I can't delete you I can find the max But it points to you I can find the min But it points to you I can find my key But it points to you They all point to you
