This is a very simple question designed to test your basic ability to program. Don't think it's hard. The input is one line, including three integers A, B, C separated by spaces (the data range is between -40 ~ 40). The output is one line, which is the calculation result of "A+B+C".
Python3 implementation
sum = 0 for n in input().split(' '): sum = sum + int(n) print(sum)
Java language implementation:
import java.util.Scanner; public class Main{ public static void main(String[] args){ Scanner sc = new Scanner(System.in); int a = sc.nextInt(); int b = sc.nextInt(); int c = sc.nextInt(); System.out.println(a+b+c); } }
