To maintain the SAT, we can think like this:
If the XOR values
Bitwise -AND Operator (&)
Participate in the operation of the two data, press bits for "and" operation.
Arithmetic Rules:0&0=0; 0&1=0; 1&0=0; 1&1=1;
That is, the two-bit is "1" at the same time, the result is "1", otherwise 0
For example: 3&5
Do you:1 Knowledge Points: "Formula derivation + Yang Hui's triangle + xor or character + feed representation"2:Define XOR or matrix elements a[i, J]:The first line enters N, M represents the Xor of N row m columns, and the second row enters n
Basic knowledge:
1. And (&) Operations (bitwise AND)The and operation is usually used for bitwise operations. For example, the result of a number and 1 is the last bit of the binary. This can be used to judge the parity of an integer. the last bit
The two values that participate in the operation, if the two corresponding bit bits are the same, the result is 0, otherwise 1.That0^0 = 0,1^0 = 1,0^1 = 1,1^1 = 03 Features of bitwise XOR:(1) 0^0=0,0^1=1 0 xor or any number = any number(2) 1^0=1,1^1=
