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>
#include<string.h>
int main(void)
{
	char S[200001],T[200001];
	int i,len,cnt;
	cnt=0;
	scanf("%s %s",S,T);
	len=strlen(S);
	for(i=0;i<len;i++){
		if(S[i]!=T[i]){
			cnt++;
		}
	}
	printf("%d\n",cnt);
	return 0;
