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>
 
int main()
{
  
  char s[101];
  char t[101];
  
  int i;
  i = 0;
  
  int n;
  n = 0; 
  
  scanf("%s",t);
  scanf("%s",s);
 
  
  while(s[i] != '\0')
  {
    if (s[i] != t[i])
    {
      n++;
    }
    i++;
  }
    printf("%d\n", n);
    return 0;
}
