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 <bits/stdc++.h>
 
using namespace std;
 
int main() {
    string s,t;
    cin>>s>>t;
    int ans=0;
    for(int i = 0;i < s.size();++i) {
        if(s[i]!=t[i])++ans;
    }
    cout<<ans<<endl;
    return 0;
