Integer Summations

Given a positive integer n, you need to compute two summations:

1. The sum of the first n natural numbers:

$$S_1=\sum_{i=1}^{n} i = \frac{n(n+1)}{2}$$

2. The sum of the squares of the first n natural numbers:

$$S_2=\sum_{i=1}^{n} i^2 = \frac{n(n+1)(2n+1)}{6}$$

Output the two results separated by a single space.

inputFormat

A single positive integer n.
