In the previous article I have already talked about 3 ways to draw curves in canvas: arc, ArcTo and Quadraticcurveto. They all have one thing in common, that is, the curves they draw can only be biased, and today's Beziercurveto and their biggest

The tree array can only implement the function of section modification and interval query, instead of the line tree without lazy tag, and the code quantity and constant are small .First define an array of int c[n]; and empty memset (c, 0, sizeof C);1
