Essential algorithms and data structures

Sorting algorithms

Routines that organise data in fundamental data structures in order.

What is a bubble sort?

The bubble sort orders an unordered list of items by comparing each item with the next one and swapping them if they are out of order.  The algorithm is finished when no swaps are made.  It effectively “bubbles up” the largest (or smallest) item to the end of the list.
