def simpleArraySum(ar): finalSum = 0 for i in range(len(ar)): finalSum += ar[i] return finalSum

python

Java

public static int simpleArraySum(List<Integer> ar) {
        return ar.stream().mapToInt(Integer::intValue).sum();
    }

With Java Stream API ;

  return ar.stream().reduce(0,(a,b) -> a+b);

def simpleArraySum(ar): # Write your code here s=0 for i in ar: s+=i

return s
