Given a positive integer **N**, the task is to represent the fraction **2 / N** as the sum of three distinct positive integers of the form **1 / m** i.e. **(2 / N) = (1 / x) + (1 / y) + (1 / z)** and print **x**, **y** and **z**.**Examples:**

Input:N = 3Output:3 4 12

(1 / 3) + (1 / 4) + (1 / 12) = ((4 + 3 + 1) / 12)

= (8 / 12) = (2 / 3) i.e. 2 / NInput:N = 28Output:28 29 812

**Approach:** It can be easily inferred that for **N = 1**, there will be no solution. For **N > 1**, **(2 / N)** can be represented as **(1 / N) + (1 / N)** and the problem gets reduced to representing it as a sum of two fractions. Now, find the difference between **(1 / N)** and **1 / (N + 1)** and get the fraction **1 / (N * (N + 1))**. Therefore, the solution is **(2 / N) = (1 / N) + (1 / (N + 1)) + (1 / (N * (N + 1)))** where **x = N**, **y = N + 1** and **z = N * (N + 1)**.
