Write a function that returns the concatenation of v1 and v2. That is, you must return a vector with the elements of v1 followed by the elements of v2.
C++ | vector<int> concatenation(const vector<int>& v1, const vector<int>& v2); |
Java | public static int[] concatenation(int[] v1, int[] v2); |
Python | concatenation(v1, v2); # returns list |
MyPy | concatenation(v1: list[int], v2: list[int]) -> list[int] |
