Distinguish between composition and inheritance as used in object-oriented programming. As part of your answer, provide examples of different situations in which each would be more appropriate.

What is meant by recursion as an algorithmic strategy in working with abstract data structures, and why is such an approach considered worthwhile? Illustrate your answer with an example sorting algorithm in Java that can be sorted linearly and recursively.

Given an alphabet of {x,y,z} possessing the following frequency distributions {1/8, 1/4, 5/8}, show how this information may be used to construct a prefix code binary tree. Given the code 11000111100, show how this is decoded using this construct.

Any ideas??

Wow that almost sounds like text book material. Heres some advice that will help you in the long run, read and read, and I can't stress it enough read. Look up tutorials online mess around with some dummy classes. This is the way you learn not by someone giving you the answer.
