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 C (GCC 9.2.1) (judge verdict: Wrong Answer)

#include <stdio.h>

int	main(int argc, char *argv[])
{
	int x;
	int ans;

	if(2 == argc)
	{
		if(argv[1][0] >= '1' && argv[1][1] > '0')
		{
			return (0);
		}
		else if(argv[1][0] == '1' && argv[1][1] == '0')
		{
			printf("%d\n",1110);
		}
		else
		{
			x = (argv[1][0]) - 48;
			ans = x + (x * x) + (x * x * x);
			printf("%d\n",ans);
		}
	}
	return (0);
}
