PPT-Binary Search Tree

vs Balanced Search Tree Why care about advanced implementations Same entries different insertion sequence 10203040506070 Not good Would like to keep tree balanced 40602050701030. This number representation uses 4 bits to store each digit from 0 to 9 For example 1999 10 0001 1001 1001 1001 in BCD BCD wastes storage space since 4 bits are used to store 10 combinations rather than the maximum possible 16 BCD is often used in b CS 46101 Section 600.
