Problem Statement

Given an integer a as input, print the value a + a^2 + a^3.

Constraints

1 \leq a \leq 10

a is an integer.

Input

Input is given from Standard Input in the following format:

a

Output

Print the value a + a^2 + a^3 as an integer.

Sample Input 1

2

Sample Output 1

14

When a = 2, we have a + a^2 + a^3 = 2 + 2^2 + 2^3 = 2 + 4 + 8 = 14.

Print the answer as an input. Outputs such as 14.0 will be judged as incorrect.

Sample Input 2

10

Sample Output 2

1110

Solution in Rust (1.42.0) (judge verdict: Wrong Answer)

use std::io::BufRead;
fn main() {
    let stdin = std::io::stdin();
    let mut handle = stdin.lock();
    let mut input1 = String::new();
    handle.read_line(&mut input1).unwrap();
    let mut input2 = String::new();
    handle.read_line(&mut input2).unwrap();
    println!("{}", input1.chars().zip(input2.chars()).filter(|(a, b)| a != b).count());
}
