WebAug 3, 2012 · A binary index tree is a data structure allowing retrieval of a value by its prefix. My understanding of binary index trees is that they are more or less analogous to tries. For example, lets say you have three numbers 1323, 1697 and 1642. You could store the numbers in a tree: 1-3-2-3 -6-9-7 -4-2 where each node represents a 10s place.
