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(The length of the byte array 8 (unsigned), search for more than 42H unsigned number and the number of bytes stored in the up unit; 42H is equal to the unsigned number of bytes stored in the equa unit; less than 42H unsigned number of bytes stored in the unit down in.
The program displays the value of up equa down.

Eight numbers: 31H, 21H, 42H, 52H, 87H, 23H, 98H, 01H)
