# Print N numbers such that their product is a Perfect Cube

Given a number **N**, the task is to find distinct **N** numbers such that their product is a perfect cube.**Examples:**

Input:N = 3Output:1, 8, 27Explanation:

Product of the output numbers = 1 * 8 * 27 = 216, which is the perfect cube of 6 (6^{3}= 216)Input:N = 2Output:1 8Explanation:

Product of the output numbers = 1 * 8 = 8, which is the perfect cube of 2 (2^{3}= 8)

**Approach:** The solution is based on the fact that

The product of the first ‘N’ Perfect Cube numbers is always a Perfect Cube.

So, the Perfect Cube of first N natural numbers will be printed as the output.**For example:**

For N = 1 => [1] Product is 1 and cube root of 1 is also 1 For N = 2 => [1, 8] Product is 8 and cube root of 8 is 2 For N = 3 => [1, 8, 27] Product is 216 and cube root of 216 is 6 and so on

Below is the implementation of the above approach:

**Performance Analysis:**

**Time Complexity:**As in the above approach, we are finding the Perfect Cube of N numbers, therefore it will take**O(N)**time.**Auxiliary Space Complexity:**As in the above approach, there are no extra space used; therefore the Auxiliary Space complexity will be**O(1)**.
