        /* note that it will report error if we write the following statement as document.write("test "+sortq(sortNumberqixy));
       note that here sortNumber is a function pointer.
        下面这句话是先执行sortq(sortNumber)，等返回值以后，再执行document.write("test "*/
        document.write("test " + sortq(sortNumber));
