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 <string.h>
int main(int argc, const char * argv[]) {
    
    char a[200000],b[200000];
    int n=0;
    
    (void)scanf("%s %s",a,b);
    
    
    for(int i=0;i<strlen(a);i++){
        if(a[i]!=b[i]){
            n=n+1;
        }
    }
    printf("%d",n);
    return 0;
}
