Complete SumSequence()'s recursive case to return the sum of the following:

• val.
• the sum of the series from val - 3 down to 3.

Ex: If the input is 11, then the output is:

26

#include using namespace std;

int SumSequence(int val) { if (val <= 3) { return val; } /* Your code goes here */

}

int main() { int val; cin >> val; cout << SumSequence(val); cout << endl; return 0; }
