$ N, m $ is given. Create a non-full $0 $ matrix of $ n \ times M $. All the grids meet the following conditions: it is an even sum of the weights of the top, bottom, and left grids. $ N, m \ Leq 40 $
You can list the differences or equations of $ n \ times M $ and $ n \ times M $ equations based on the conditions in the question. (The equations mean that all positions are $1 $ or $0 $, the answers in the rightmost column need to be generated in the sense of $ mod \, 2 $ through equation
Do you want to learn C ++ well?
Do you want to be proficient in C ++ in a short time?
The 21-day master of C ++ is no longer a myth. The following is my dedicated secret, showing the truth!
After reading my exclusive secret, is it true that everyone has been attacked? In fact, this cartoon comes from the Internet. Although the content is banter, it doesn't make sense if you try it carefully.
To illustrate this problem, let's talk abou

Bitwise exclusive or operation ^, operation ^
Bitwise xor (xor): If A xor B is equal to A and B, the result is 0. If the corresponding bits are not equal, the result is 1.
Rule:
A number is different from 0 or equal to itself: 0 ^ 0 = 0 1 ^ 0 = 1
A number is different from 1 or equal to 0 ^ 1 = 1 1 ^ 1 = 0
A number is different from itself or equal to 0: a ^ a = 0
Application:
Exchange two numbers a and B without intermediate Variables
A = a ^

Carefully observed, 203879 is a 6-digit number, and its number on each digit is different, and it does not appear on all digits after the square to make its own number.There is a 6-digit number with this feature, please find it!Let's summarize the screening requirements:1.6-bit positive integer2. The numbers on each digit are different3. Each digi
difference or. Then each node holds the XOR value of its parent node, and when you set the value of each node to different or odd times, then you will be different or a different value if you have a parent node that is different. If this parent is a virtual node n, that's okay because the D value of n is 0, xor or it equals itself. But if it's not n then it can't be judged. Because this multi-XOR or parent node value does not know what its D value is. so we use D[i] to denote the XOR value of

AlgorithmThe problem is that operations on the buffer zone do not need to be mutually exclusive ~ Mutex semaphores in the Tang Zi notebook
After all, they all have different in and out pointers. Can they operate on different buffers? When looking at producer and consumer issues, we need to access critical resources (buffers) at the same time of the process.

Discover a new knowledge and introduce it to you:
Binary exclusive or operation:The two are equal to 0, not equal to 1.
In this way, we find that the third parameter is not required when two integers are exchanged.For example, a = 11, B = 9. The following is binary.A = a ^ B = 1011 ^ 1001 = 0010;B = B ^ A = 1001 ^ 0010 = 1011;A = a ^ B = 0010 ^ 1011 = 1001;In this case, a = 9 and B = 11.
For example, you can exchange two Mc positions by pressing on
