Sorting algorithm and array

If the search ends with an empty half, the condition cannot be fulfilled and target is not found. What is the best-case runtime complexity? Algorithmic time vs. We define three references at the front of each array. If we have total n elements, then we need to repeat this process for n-1 times.

A user might want to have the previous chosen sort orders preserved on the screen and a stable sort algorithm can do that. If the data is reverse-sorted, each item must travel to the head of the list, and this becomes bubble-sort.

Creating a useful dictionary requires that words be put in alphabetical order.

How does it work? O N clearly is the minimum sorting time possible, since we must examine every element at least once how can you sort an item you do not even examine? Stability is also not an issue if all keys are different.

You can choose a random item, or median-of-three front, middle, end. Suppose we have N elements. A lower bound is a mathematical argument saying you can't hope to go faster than a certain amount.
