Minimize sum of an array having Bitwise AND of all its pairs present in a given matrix | Function to find the minimum sum of the array such that Bitwise AND of arr [ i ] ana arr [ j ] is mat [ i ] [ j ].
Stores the minimum possible sum.
Traverse the range [ 0 , N - 1 ].
Stores the Bitwise OR of all the element of a row.
Traverse the range [ 0 , N - 1 ].
If i not equal to j.
Update the value of res.
Increment the sum by res.
Return minimum possible sum.

How can the above be solved in Python?
 ... Give me a code to minimize sum of an array having Bitwise AND of all its pairs present in a given matrix and the other steps required?
