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 (Clang 10.0.0) (judge verdict: Wrong Answer)

#include <stdio.h>
#include <stdlib.h>
#define repeat(a, n) for (int i = a; i < n;i++)
int main()
{
    int n,m,k,j=0,l=0,c=0,d=0;
    scanf("%d %d %d", &n,&m,&k);
    int a[n], b[m];
    repeat(0, n) scanf("%d", &a[i]);
    repeat(0, m) scanf("%d", &b[i]);
    while(j<n,l<m){
        c += a[j] + b[l];
        d += 2;
        if (c==k){
            printf("%d", d);
            break;
        }
        if (c>k)
        {
            printf("%d", d - 1);
            break;
        }
        j++;
        k++;
    }
}
