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] |
