Sometimes in the form of the continuous GDI + operation will occur when the flash, in addition to modify the form parameters, should also solve the problem of the refresh itself, double buffering may be the case.

For example, the SWIFT array has a map (_:) method that takes a closure expression as its only parameter, which is run once on each element of the array, returns a new element correspondin

Question:Give you n points, m RayFind a polygon so that the area of the polygon is divided by the number of interior mines of the polygon to the minimum value.If you think about it, it's okay to find the triangle with the smallest ratio, because the ratio of other triangles is larger than that of the triangle. After the triangle is combined into a polygon, it is bound to increase the ratio.Therefore, we can enumerate the triangle directly by using brute force O (n ^ 3) and calculate the ratio of
