Bitwise AND Sum

Given a list of integers, write a program that calculates the sum of all distinct values produced by the bitwise AND operation on all pairs of integers from the list. Input format: - The first line contains an integer N (1 <= N <= 1000), the size of the list. - The second line contains N space-separated integers (0 <= A[i] <= 10^4). Output format: - Output a single integer representing the sum of the distinct AND values. Example: Input: 4 2 3 5 7 Output: 8 (AND pairs: 2&3, 2&5, 2&7, 3&5, etc. resulting in distinct values: 0, 2, 3, 5, 6, 7 which sum to 8)
