for the symbol bit, all bits are reversed.Solve the problem of adding and subtraction operations, but still have a plus or minus 0 points, and then to the complement　　　　　　　　What is the complement?The complement of a positive number is the same as the original code, and the complement of the negative number is the inverse of all the bits in the original code except for the sign bit (get the inverse code), then the lowest bit plus 1.Or an example to illustrate:The 3 complement of the int type is:

First, introduce several concepts: GCD, queue, serial, parallel, synchronous, asynchronous. GCD (Grand Central Dispatch ): The Great Apple developed a multi-core multi-thread solution. Is a C language-based underlying API Defining tasks with blocks is flexible and convenient to use. Provides more control capabilities and underlying functions not available in the Operation queue The basic idea of GCD is to put the operation s

IOS development-CGAffineTransformMakeRotation changed the central solution Poor Dad. It took two hours to solve the problem. Annoying .. When I wrote a clock demo today, CGAffineTransformMakeRotation was used for clockwise rotation. the rotation of an image is centered on the image itself, that is, its center is fixed during the rotation process. The effect is the same as that of our hour hands. For example, the Code for rotating the hour hand, minut
