In this challenge, you are required to calculate and print the sum of the elements in an array, keeping in mind that some of those integers may be quite large.
- Function Description
- Complete the aVeryBigSum function in the editor below. It must return the sum of all array elements.
- aVeryBigSum has the following parameter(s):
- int ar[n]: an array of integers.
- Return
- int: the sum of all array elements
- Input Format
- The first line of the input consists of an integer n.
- The next line contains n space-separated integers contained in the array.
- Output Format
- Return the integer sum of the elements in the array.
- Constraints
- 1 <= n <= 10
- 0 <= ar[i] <= 10^10
문제풀이
- arr가 주어지고, 그것의 합을 구하라는 문제
- 그냥 sum함수 쓰면됨
