用汇编语言 统计带符号数

Question

在BUF1和BUF2两个数据区中，各定义有10个带符号字数据，范围-20~20.试编制一完整的源程序.编程序统计数据块中0~10,10~20,-10~0,-20~-10的个数并求最大值和最小值
希望各位高人帮帮忙```答案越多越好~~~ 时间有限 在线等 谢谢!!

自己手写的阿，一定要给分阿，已验证了

Answer 2

额````分数那么高 可惜偶不知道诶 路过~~~~~

Answer 3

题目在清楚点,有很多疑惑,是求2个数据区一起的个数和最大最小,还是分别求呢?

求buf2的话，把前面的buf1换成buf2 就可以了，或者复制一下，改数据就可以把两个部分全部统计了。
