The server generates a function $f$ of one real variable, containing parameters ${a}_{1}$, ${a}_{2}$,..., hich is defined by different formulas on two segments of an interval. Your aim is to find values for these parameters ${a}_{i}$ such that $f$ is continuous and differentiable to a required order.

One can solve the problem either by a Taylor expansion, or by successive derivations. In the difficult cases, the resolution of a system of linear equations is also necessary.
