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 JavaScript (Node.js 12.16.1) (judge verdict: Accepted)

// inputに入力データ全体が入る
function Main(input) {
	var ans = 0
	// 1行目がinput[0], 2行目がinput[1], …に入る
	input = input.trim().split("\n")
	// var arr = input.trim().split("\n")
	// var n = input[0].split(' ').map(n => parseInt(n))
	var i = parseInt(input)
	ans = i + (i * i ) + (i * i * i)

	//出力
	console.log(ans)
}
//*この行以降は編集しないでください（標準入出力から一度に読み込み、Mainを呼び出します）
Main(require("fs").readFileSync("/dev/stdin", "utf8"));
//Main(require('fs').readFileSync('./input.txt', 'utf-8'));
