Array difference P46584
Write a function that returns a sorted vector with the difference of the sorted vectors v1 and v2. The result must have the elements in v1 that are not in v2, without repetitions. For instance, the result of the difference of a vector with 1, 2, 2, 5, 5 and 7 and a vector with 2, 3, 3 and 7 is a vector with 1 and 5.
Interface
| C++ | vector<double> difference(const vector<double>& v1, const vector<double>& v2); |
| Java | public static double[] difference(double[] v1, double[] v2); |
| Python | difference(v1, v2) # returns list |
difference(v1: list[float], v2: list[float]) -> list[float] |
