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>

int main(void) {
  char S[200001];
  char T[200001];
  int i, j;
  int num = 0;
  
  scanf("%s", &S);
  scanf("%s", &T);
  for(i=0; S[i]!='\0'; ++i);
  for(j = 0; j <= i; j++){
    if(S[j] != T[j]){
      num++;
    }
  }  
  printf("%d", num);
  return 0;
