在实现文件系统时，为了加快文件目录的检索速度，可用“文件控制块分解法”。假设目录文件存放在磁盘上，每个盘块为512B.文件控制块占64B，其中文件名占8B。通常将文件控制块分解成两个部分，第1部分占10B (包括文件名和文件内部号)，第2部分占56 B (包括文件内部号和文件其他描述信息)。   1.假设某个目录文件共有254个文件控制块，试分别给出采用分解法前后，查找该目录文件的某个文件控制块的平均访句磁盘次数。   2.一般地，若目录文件分解前占用 n 个盘块，分解后改用 m 个盘块存放文件名和文件内部号，请给出访问磁盘次数减少的条件。

Expression evaluation is a classic problem. In this problem, you only need to evaluate an expression of length less than . It only contains non-negative integers (possibly with leading zeros), `+’s, `-‘s and `*’s, i.e., it satisfies the following grammar: <expression>:= <term>|<expression>+<term>|<expression>-<term> <term>:= <number>|<term>*<number> <number>:= <digit>|<number><digit> <digit>:= 0|1|2|3|4|5|6|7|8|9 For example,013, 0213-2132*0213 are valid, but -2132 and 32113+-3213 are invalid. The result of the evaluation may be too large or negative. Output the result modulo  to avoid overflow since you will use a -bit machine. The -bit machine contains units of memory, denoted as , , , .

You need to set the initial value for each unit such that the machine can stop in finite cycles and output the result of expression modulo . Since there is a time limit for a problem. In this problem, the machine can execute at most cycles.
