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

**Examples:**

Input:N = 3

Output:1, 8, 27

Explanation:

Product of the output numbers = 1 * 8 * 27 = 216, which is the perfect cube of 6 (6^{3}= 216)

Input:N = 2

Output:1 8

Explanation:

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:

## C++

`// C++ program to find N numbers such that ` `// their product is a perfect cube ` ` ` `#include <bits/stdc++.h> ` `using` `namespace` `std; ` ` ` `// Function to find the N numbers such ` `//that their product is a perfect cube ` `void` `findNumbers(` `int` `N) ` `{ ` ` ` `int` `i = 1; ` ` ` ` ` `// Loop to traverse each ` `//number from 1 to N ` ` ` `while` `(i <= N) { ` ` ` `// Print the cube of i ` `//as the ith term of the output ` ` ` `cout << (i * i * i) ` ` ` `<< ` `" "` `; ` ` ` ` ` `i++; ` ` ` `} ` `} ` ` ` `// Driver Code ` `int` `main() ` `{ ` ` ` `int` `N = 4; ` ` ` ` ` `// Function Call ` ` ` `findNumbers(N); ` `} ` |

**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)**.
