A balanced tree can store a list while providing all operations of both dynamic arrays and linked lists reasonably efficiently, but both insertion at the end and iteration over the list are slower than for a dynamic array, in theory and in practice, due to non-contiguous storage and tree traversal / manipulation overhead.

The number of nodes at the tree level is equal to the actual vocabulary size of words with the length in a given sequence; the number of nodes in the most balanced tree, which corresponds to the most complex sequence of length N, at the tree level is either 4 i or N-j + 1, whichever is smaller.

This does not seem like an advantage, since normally " k " e " log " n ", but in a balanced tree every comparison is a string comparison requiring O ( " k " ) worst-case time, many of which are slow in practice due to long common prefixes ( in the case where comparisons begin at the start of the string ).
