此函数从请求中提取一个32位整数，并使用它中的算术运算来计算一个动态缓冲区的大小。
This function takes a 32-bit integer from the request, and USES it in an arithmetic operation that calculates the size of a dynamic buffer.
我只添加了psyco . bind (main)这一行，而不是添加一个总的psyco . jit调用，因为main函数确实要循环多次(但是仅利用了最少的整数运算)。
Call, I added only the line psyco.bind (main), since the main function does loop a number of times (but only makes minimal use of integer arithmetic).
本文提出一种新的算法，它是从开关函数最小项集合所对应的整数集出发，通过对整数进行算术运算，从而求得接近最小的两级与一或表达式。
An algorithm for such purpose, quite different from any others so far known, is here presented on the basis of arithmetic operations on integers, which correspond to the minterms of the function.
