Muitiway Search Tree Definition/Meaning:
Muitiway search tree of degree n. A generalization of a binary
search tree to a tree of degree n where each node in the ordered tree has m
≤ n children and contains (m-1) ordered key values, called subkeys. For some given search key, if the key is less than the first subkey
then the first subtree (if it exists) is searched for the key; if the key lies
between the ith and (i + l)th subkey, where
i = 1,2,.....,m - 2
then the (i + l)th subtree (if it exists) is searched; if the key is greater
than the last subkey then the mth subtree (if it exists) is searched.
