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 Kotlin (1.3.71) (judge verdict: Accepted)


fun main(args: Array<String>) {
    // var numberTests = readLine()!!.toInt()
    // var results = mutableListOf<String>()

    // for (i in 0..numberTests-1) {
    var tmpLine = readLine()

    
    val result = experiment(tmpLine!!.toInt())
    // results.add(result)
    // }

    // for (result in results) {
        println(result)
    // }
}

fun experiment(a: Int) : String {

    var result = a + a * a + a * a * a

    return result.toString()
}
