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

#include<ctype.h>



int main()

{
    int count=0;
    char s[20001],t[20001];
    scanf("%s %s",s,t);
    int len=strlen(t);
    for(int i=0;i<len;i++)
    {
        if(s[i]!=t[i])
        {
            s[i]=t[i];
            count++;
        }
    }
    printf("%d\n",count);


    return 0;
}
