Doubling Grains on a Chessboard

Square 1 holds one grain. Each later square holds twice as many grains as the previous square. Return both the count on the requested square and the total on squares 1 through 64. Write each count as decimal text, because the board total is too large for a signed 64-bit integer.

Implement chessboard_grains(square).

Input

square: The requested square, numbered from 1.

Output

Return two decimal strings: [count on the requested square, total on all 64 squares].

Vincoli

1 ≤ square ≤ 64. Output strings contain decimal digits only, with no commas, spaces, or leading zeros.

Esempi
