Noob Mathematician
CodeChefOpen on judge ↗
Chefina, the noob mathematician is a third year student at SRM. She is now learning the addition operation. The professor has written down the sum of multiple numbers. She should calculate the sum. To make the calculation easier, the sum only contains numbers 1, 2 and 3. Still, that isn't enough for Chefina. She is only beginning to count, so she can calculate a sum only if the summands follow in
