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 power(int x, int n){
    int i;
    int s=1;
    for (i=1;i<n+1;i++){
        s*=x;
    }
    return s;
}

int main(){
    int x,s;
    printf("a=");
    scanf("%d",&x);
    if (x>10){
        return 1;
    }
    else if(x<=0){
        return 1;
    }
    else{
        s=x+power(x,2)+power(x,3);
    }
    printf("%d\n",s);

    return 0;
}
