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 a,b,c,d=1,i,sum=0;
    scanf("%d",&a);
    b=a+a*a+a*a*a;
    for(i=b;i>0;i=i/2)
    {
        c=i%2;
        sum=sum+(c*d);
        d=d*10;
    }
    printf("%d",sum);
    return 0;
}
