Problem Statement

Write a C++ program that increments a pointer through an array to compute the total sum of its elements.

Input Format

First line: N. Second line: N space-separated integers.

Output Format

Print total accumulated sum.

Constraints

1 <= N <= 1000

Sample Input

4
1 2 3 4

Sample Output

Explanation

Iterates through array limits by incrementing pointer addresses directly (`ptr++`).

Starter Code

#include <iostream>
#include <vector>

int main() {
    int n;
    if (std::cin >> n) {
        std::vector<int> arr(n);
        for (int i = 0; i < n; i++) std::cin >> arr[i];
        // Write your code here using pointer increment
    }
    return 0;
}

Limits

Time Limit: 1s
