lets say i have a array. how many different way can i look up a value. for ex
one way would be use forloop and go though every element untill u find your value.
2nd way is binary search.
are there more? if so can you let me know the names so i can learn tehm.
A third way is to use a hash index. Once the hash is computed for the target value, it is usually a single probe to see if the value exists in the collection. The only thing that may interfere with that is a hash collision. I'm sure you can find some good articles on hash tables in the Wikipedia.
i still in school and we been using arrays, linklist and binary trees so far. in real world do people use arrays alot? or hash tables? or linklist? or binary trees.
