In three-dimensional space, a point around the x-axis y-axis z-axis rotation of a certain radian after the coordinates of the new point is easy to calculate, the problem is if it is the rotation axis is an arbitrary vector (x, y, z), how to know the rotation of angle radian after the new point coordinates it. In OpenGL there is a function Glrotatef (ANGLE,X,Y,Z)

A technical project manager can easily make the following mistake:When assigning tasks to members for self-thought-simple problems, technical details are introduced and the simplicity of the problems is revealed..For example, the project manager x needs to change a string on the page when receiving a new requirement from the customer.

The initial values all point to the header. slow moves one step forward each time, and fast moves two steps forward each time. If the linked list has a ring, fast must first enter the ring, when slow enters the ring, the two pointers must meet each other and set the collision point to
