When one is given input such as : [[1,2,3],[1,2,3],[3,3,1]] (the values in column stands for the cost of materials)

The output : 4

So you have to:

Select  material-1 of cost 1 in first house(row)

Select  material-2 of cost 2 in second house(row)

Select   material-3 of cost 1 in third house (row)

total = 1+2+1 -> 4
