Problem Statement

Write a C++ program comparing pointer addresses of array elements using relational operators (“).

Input Format

First line: N. Second line: N space-separated integers. Third line: Two indices i and j.

Output Format

Print 'Before' if pointer at i comes before pointer at j, otherwise 'After' or 'Equal'.

Constraints

1 <= N <= 1000, 0 <= i, j < N

Sample Input

5
10 20 30 40 50
1 3

Sample Output

Before

Explanation

Relational operators compare memory addresses of pointers belonging to the same array.

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];
        int i, j;
        std::cin >> i >> j;
        // Write your code here
    }
    return 0;
}
