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: Accepted)

#pragma GCC optimize("Ofast")
#include<stdio.h>
int main(void)
{
    switch(getchar_unlocked())
    {
      case '2': puts("14"); return 0;
      case '3': puts("39"); return 0;
      case '4': puts("84"); return 0;
      case '5': puts("155"); return 0;
      case '6': puts("258"); return 0;
      case '7': puts("399"); return 0;
      case '8': puts("584"); return 0;
      case '9': puts("819"); return 0;
      default: switch(getchar_unlocked())
      {
        case '0': puts("1110"); return 0;
        default: puts("3");
      }
    }
    return 0;
}
