输入若干个数值存入数组中，采用冒泡算法进行升序或降序排序

[12:38:09 root@centos8 ~]#bash sort.sh
before sort:
14756 26459 13397 30603 24422 17590 16022 5566 10825 20888 1210 220 9242 11466 6855 7255 9758 5254 28678 17400
after sort:
30603 28678 26459 24422 20888 17590 17400 16022 14756 13397 11466 10825 9758 9242 7255 6855 5566 5254 1210 220
The max integer is 30603,the min integer is 220
