I need help with this question

Type the exact output produced by the following program. #include #include using namespace std; int aTest(int value); int main (void) { cout << aTest(4) << endl; return EXIT_SUCCESS; }

int aTest (int value) { int returnVal; if (value == 1) { returnVal = 1; } else { returnVal = value * 2 + aTest(value - 1); } return returnVal; }

Can you show me the steps on how you got the output?
