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 <math.h>

int main(){
    char a[200000];
    char b[200000];

    scanf("%s", a);
    scanf("%s", b);

    int count = 0;
    for (int i = 0; i < sizeof(a); i++){
        if (a[i] != b[i]) count++;
        if (a[i] == '\0') break;
    }

    printf("%d", count);

    return 0;
}
