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<stdio.h>
int main(){
    char a[10001];
    char b[10001];
    int i, count = 0, ans = 0;
    if(scanf("%s %s", a, b) < 2){
        printf("%d\n", ans);
        return 0;
    }
    for(i = 0; i >= 0; i++){
        if(a[i] == '\0'){
            break;
        }else{
            count++;
        }
    }
    for(i = 0; i < count; i++){
        if(a[i] != b[i]){
            ans++;
        }
    }
    printf("%d\n", ans);
    return 0;
}
