Binary search tree vs hash table

WebHash Table vs Binary Search Trees. Hash Tables. Simpler to code. No effective alternative for unordered keys. Faster for simple keys (a few arithmetic ops versus log N compares). Better system support in Java for strings (e.g., cached hash code). Binary Search Trees. Stronger performance guarantee.

WebTree (data structure) This unsorted tree has non-unique values and is non-binary, because the number of children varies from one (e.g. node 9) to three (node 7). The root node, at the top, has no parent. In computer science, a tree is a widely used abstract data type that represents a hierarchical tree structure with a set of connected nodes ...

WebA list is acceptable to use as a table entry because while traversal is O(n), the lists tend to be short assuming the hash table is sufficiently large and the objects stored in the table are hashed using a good quality hashing algorithm.
