冒泡排序（Bubble Sort），是一种计算机科学领域的较简单的排序算法。
它重复地走访过要排序的数列，一次比较两个元素，如果他们的顺序错误就把他们交换过来。走访数列的工作是重复地进行直到没有再需要交换，也就是说该数列已经排序完成。(Bubble sorting is a simpler sorting algorithm in the field of computer science.
It repeats the sequence of the sequence, and compares two elements at a time and exchange them if they are in the wrong order. The work of visiting the series is repeated until no exchange is needed, that is, the sequence has been sorted.)
