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>
#include <stdlib.h>
#include <string.h>



int main(){
    int n;
    char buf[30];

    printf("nを入力してください");
    //標準入力から1行bufに格納
    fgets(buf, sizeof(buf), stdin);

    n=atoi(buf);

    if (n>10){
        printf("ERROR\n");
    }
    else if (n<0){
        printf("ERROR\n");
    }
    else{
        int result = n+n*n+n*n*n;
        printf("%d\n", result);

    }

    
    return 0;
