Problem:
Score : 100 points

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 Python (3.8.2) (judge verdict: Wrong Answer)

from typing import List

LOCAL = False

if LOCAL:
    import os
    import sys
    import time
    start = time.time()
    # For getting input from input.txt file
    letter = "A"
    sys.stdin = open(f'{letter}in.txt', 'r')

    # Printing the Output to output.txt file
    sys.stdout = open(f'{letter}out.txt', 'w')

#### START ####


def calculate(s: int):
    print(s + s**2 + s**3)

s = int(input())

#### END ####
if LOCAL:
    print('TIME:', time.time()-start, 'sec.')
