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(void){
    int N,M,K;

    cin >> N >> M >> K;

    int A[N],B[M],AB[N+M];

    for(int i = 0; i < N; i++){
        cin >> A[i];
        AB[i] = A[i];
    }
    for(int i = 0; i < M; i++){
        cin >> B[i];
        AB[i + N] = B[i];
    }
    //for(int i = 0; i < N +M; i++){
    //    cout << AB[i] << " ";
    //}
    int cnt = 0;
    int sum = 0;
    for(int i = 0; i < N + M; i++){
        for(int j = N + M -1; j > i; j--){
            if(AB[j] < AB[j -1])swap(AB[j],AB[j-1]);
        }
        sum += AB[i];
        if(sum <= K){
            cnt++;
        }else{
            break;
        }
    }
    cout << cnt << endl;
