Learn how to use tries and binary indexed trees for efficient search implementations.
Continue your Python 3 learning journey with Learn Advanced Data Structures with Python: Trees. Learn how to use prefix trees, or tries for short, tree-like data structures in which each node contains links to nodes representing characters. Then learn how to use binary index trees to compute an accumulation in O(logn) time.



### Notes on Prerequisites
