Apply \(a^3\pm b^3=(a\pm b)(a^2\ mp ab+b^2)V : \((y + 3) (y^[2} - y \times 3 + 3^{2}) V
Multiply the monomials: \((y + 3) (y^{2} -3y + 3^{23) V
Calculate the power: \((y + 3) (y^{2} - 3 y + 9) V

Explanation:
The building of a hacker rank is one that cost a lot of money and as such the minimum cost is 4.
What is the minimum cost?
The minimum cost is the lowest cost that is needed to complete a building. It depends on:
- The cost of each type of house to be built (e.g. cost of a wood house, cost of a brick house, etc.)
- The number of the type of house to be built e.g. 2 03 3 or even more.
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
