1. Set the $A, b,c$ is a subset of the collection $M $, please prove: $$\bex (C\subset A) \wedge (C\subset b) \lra (C\subset a\cap b). \eex$$Proof: clearly established.2. Set the set $X $ meet $\bar{\bar \bbn}\leq \bar{\bar x}$. Please prove: Collection $Y =x\cup\bbn$ meet $\bar{\bar X}=\bar{\bar y}$.Proof: Apparently $\bar{\bar X}\leq \bar{\bar y}$. On the other hand, by $\bar{\bar N}\leq \bar{\bar x}$ know $X $ by a subset $A $, $$\bex y=x\cup\bbn = (X\bs a) \cup (A\CUP\BBN) \sim (X\bs a) \cup

AAD prepares for the division below, which consists of a decimal number of the AL and AH two single BCD codes.1. AAD (adjust except)5.2 The instruction is used to adjust the value of the Register AH and Al before division, it is a decimal value of the single BCD code in the two registers, and its adjustment rules are as follows:Al←ah*10+al,ah←0Affected flag bits:

System program designer, the circle cut into a lot of segments, these line interface is called the port (colloquially is the fracture, is interrupted), When the system runs to these ports, a look at whether the port is turned on or off, if it is closed, the rope is connected, the system runs down, if the port is open, the system will get commands, external data input, accept external data and execute. Where the main 8259A and the corresponding port address from 8259A are 20h/21h and a0h/a1h. th

the arrays cannot be added and deleted. This is not very flexible, for this C # provides ArrayList for handling dynamic arrays. ArrayList after the creation can be based on the actual needs of the element additions and deletions. This is very useful. Let's look at the next ArrayList constructor. ArrayList al = new ArrayList (); Let's look at a simple example: ArrayList al = new ArrayList (); Console.W

address in the address space. The CPU can directly read and write data directly from three places: memory address space, port, CPU internal register. 14.1-Port Read/writethe CPU and the chip on which the port resides are connected via address bus, so the port address and memory address are transmitted via address bus. In a PC system, the CPU can locate up to 64KB different ports. The address range for the port is 0~65535.The read/write to the port can only be used in and out instructions. diff
