How is the sameness of keys in two 2-3 trees different from the sameness of information in two 2-3 trees?

Question

Algorithms

Two 2-3 trees of the same length are given, the keys of which are in the same range. What will mean the same information between these two trees in any node? How does the identity of keys in these two trees differ from the identity of information in these two trees? What does the phrase "the sameness of keys may not mean the sameness of information" mean in this case?

Answer 1

because data is a key-value pair. Therefore, there are three options: the
keys are different, the values ​​are the same
, the keys are the same, the values ​​are different
, the keys are different, the values ​​are different.
