Here we can print this node right here. If we only knew the 11, this max level here would be 11 or greater. However, even if the value was greater than 11, the next node up would still take the five senses of mean level. That means that we actually don’t need to check the four node because it’s irrelevant. And thus we can prune it from the tree. We can’t prune any other nodes or branches in this situation.
