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(void){
  char s1[200000],s2[200000];
  int i,l;
  l=200000;
  int ans=0;
  for(i=0;i<l;i++){
    s1[i]='0';s2[i]='0';
  }
  scanf("%s",s1);
  scanf("%s",s2);
  for(i=0;i<l;i++){
    if(s1[i]!=s2[i]){ans++;};
  }
  printf("%d",ans);
        
  return 0;
