The previous log talked about bit operations.   Bit operators: (1 ),~ Reverse retrieval ~ 0011 = 1100 (2), & bits and 0011 & 0110 = 0010 (3), | bit or 0011 | 0110 = 0111 (4) ^ exclusive or 0011 ^ 0110 = 0101     There are two questions

N count Calculate the number of K numbers from N to the same or, and the total value (CNK values (which may be the same) obtained in all cases is K from 1 to n Output n count     At the beginning, I had no thoughts on this question. I didn't mean

Petar maymounkov and David mazi' eresfpetar, dmg@cs.nyu.eduhttp: // kademlia.scs.cs.nyu.edu SummaryThis article describes a point-to-point (P2P) system with verifiable stability and high performance stability in an error-prone network environment.

We all know that we can use A ^ = B;B ^ =;A ^ = B; To exchange the values of A and B. Here I will talk about the principle:^ In C, the bitwise XOR operator is used. If the bitwise XOR operator is used, the result is 0. If it is different, the result

When I read a book today, I see: "The characteristics of the exclusive or operation are: if a ^ B = C, then C ^ B = A and C ^ A = B. This rule can be used ." I plan to give it a try. I first assume that there is a key and then the number is given.
