I am woking on an Assigment.
The Problem is to Create a Comptuer Based Dictionary of English Language using any of the Data Stucture Technique.

I am in the planning phase of it.

My Question is which data stucture technique will be simple and easy to implement.
Tree, Bianry Tree, Ques, Stack or any other simple type.

I have very limited time for doing so. Plz suggest as early as possible. If u could send me any sample code. Then it will be again a great help for me.

Thanks

It really depends on what kind of behavior your looking for. E.g. constant lookup time vs. constant insertion time etc. Think in terms of what you need the data source to be able to do for you in order to solve your problem, then find the data structure which supports it.

A dictionary is a pretty big structure.
The problem sounds like it would be solved easily with a Map or some sort.
A mapping of words to their definitions.

If you want to be able lookup a definition given a word, I would recommend a HashMap.
Elements are accessed in O(1) time. However, the tradeoff, is a chaotic ordering.
If you want things in order, you probably want a TreeMap. The keys (the words) are in sorted
order and you can browse them easily. The cost is still a respectible O(lg N). The call is yours to make.
