前些时候做过的一份面试试题[3]

                                      if (ai[i] > ai[i+1])  swap(ref ai[i], ref ai[i+1]);

                   }

         }

         static void swap(ref int x,ref int y) {

                   x = x + y;

                   y = x - y;

                   x = x - y;

         }

         static void main(string[] args) {

                   int[] ai = getdata();

                   bubblesort(ai);

                   foreach (int i in ai) console.writeline(i);
