Problem

How many squares are there on a chessboard?

Generalize the question for an n x n chessboard, counting every square size, not only the individual cells. Implement count_squares(n), which accepts a positive integer and returns the total number of axis-aligned squares.

For example, a standard 8 x 8 chessboard contains 204 squares.

Constraints

1 <= n <= 10^9
Count only axis-aligned squares whose sides follow the board grid
Return the total number of squares
