在长度为8的字节数组（无符号数）中，查找大于42H的无符号数的个数，存放在字节单元up中；等于42H的无符号数的个数，存放在字节单元equa中；小于42H的无符号数的个数，存放在字节单元down中。

　　程序显示up equa down的值。

　　

　　八个数：31H,21H,42H,52H,87H,23H,98H,01H-Length byte array (unsigned) Find the number of unsigned greater than 42H, stored in a byte unit up　equal 42H unsigned number, stored in a byte unit equa　less than 42H unsigned number, storage in byte unit down. Program show up equa down the value. Eight number: 31H, 21H, 42H, 52H, 87H, 23H, 98H, 01H
