1. Number conversion, complement anti-codeConversion of the numbering:Binary--Decimal (add by right expansion)Decimal---binary (with the exception of the second and last obtained as the most significant bit)Decimal decimal number, binary decimal, rounding by twoHex Notation number notation:Original code: Highest bit represents sign bit, 0 is positive, 1 is negativeInverse code: Positive number of the invers

2.65int even_ones (unsigned x)Requirements: Return 1 when x contains an even number of 1s; 0 otherwise. Suppose an int has a w=32 bit.Analysis: The most expected use is a loop, but the loop statement cannot be used. If one is written in a statement, it takes 32 times; Here the dichotomy is used, then the operation becomes Log232 = 5 times. The dichotomy implies a loop and simplifies the loop traversal. How to use the dichotomy method?The title is to J

Computer Network review: Topic 1. How does the Internet organize its connection structure?1. essential differences between early "networks" and modern networks:Early "network": Host-centricModern Network: group-based exchange network2. The network and the network are connected through routers to form a network with a wider coverage.3. computers connected to the I

messages, so that the application can be notified when only part of the continuous message is completed, in this way, the data seen in the presentation layer is continuous. In some cases, if the presentation layer receives all the data, the data is used to represent the presentation layer. Example: RPC and SQL.Transport layer OSIThis layer of function includes whether to select the error recovery protocol or error-free recovery protocol, and reuse the data stream input of different applications

subscript starts at 0--the subscript of the first element of the array is 0. The subscript of the last element is the array length minus 1. The subscript operation returns an Lvalue, which can be used as the left operand of an assignment operation, equivalent to assigning a new value to the element referenced by the subscript. Operator ( operator)The fetch address operator requires an operand whose only operand must be an Lvalue object, which returns

little ashamed. I have not really engaged in several open-source projects. I have read some open-source projects written by others. In the next two months, I plan to build a distributed open-source crawler, crawl SNS data such as the human network, and publish it to the public. I feel that most of my labs are full of mixed life and there are only a few things I really want to do. In this environment, we need to strengthen our own recuperation and access more technologies. I hope to read more b

that the human eye is not sensitive to the image due to insufficient illumination.　　McCann AlgorithmThis algorithm is intended to produce a better estimate of the uneven illumination, the extraction of the control information is no longer the weighted mode of the Gaussian convolution, but the intensity of a spiral is selected to be weighted, compared with the Gaussian weighting so that the greater range of illumination information can be obtained, and the specified number of iterations based on
