Given a DNA sequence database where each sequence is a string composed of characters “A”, “G”, “C” and “T”, we use a Trie data structure to efficiently handle operations such as searching for specific DNA sequences and finding common prefixes. Suppose we have n sequences of DNA, with lengths ranging from 3 to m. Answer the space and time complexity with Big-O notation. The maximum depth of the Trie is [depth]. The maximum space complexity of the Trie is  [space].  The worst case time complexity of searching a string in the Trie is [time].
