Bubble Sort - Algorithm Introduction
This section describes the Bubble Sort algorithm - A simple and slow sorting algorithm that repeatedly steps through the collection, compares each pair of adjacent elements and swaps them if they are in the wrong order.
Bubble Sort is a simple and slow sorting algorithm that repeatedly steps through the collection, compares each pair of adjacent elements and swaps them if they are in the wrong order.
The basic idea of Bubble Sort algorithm can be described as these steps:
1. Data elements are grouped into two sections: a sorted section and an un-sorted section.
2. Go through every element in the un-sorted section and re-arrange its position with its neighbor to put the element with higher order on the higher position. At the end, the element with the highest order will be on top of the un-sorted section, and moved to the bottom of the sorted section.
3. Repeat step 2 until no more elements left in the un-sorted section.
In the sorting algorithm, if you watch the move of the elements with higher orders, they are like bubbles in the water, floating slowly from the bottom to the top.
