Sum of Bitwise AND of all unordered triplets of an array | Function to calculate sum of Bitwise AND of all unordered triplets from a given array such that ( i < j < k ).
Stores the resultant sum of Bitwise AND of all triplets.
Traverse over all the bits.
Count number of elements with the current bit set.
There are ( cnt ) C ( 3 ) numbers with the current bit set and each triplet contributes 2 ^ bit to the result.
Return the resultant sum.

How can the above be solved in Python?

=====
Can you provide a code to sum of Bitwise AND of all unordered triplets of an array and the other steps required?
