Basic Accuracy: 31.66% Submissions: 60 Points: 1

A pronic number is a number which is the product of two consecutive integers. Find all Pronic Numbers less than  or equal to the given integer N.
The first few Pronic numbers are: 0, 2, 6, 12, 20, 30, 42, 56, 72, 90, 110, 132 and so on.

Example 1:

Input:
N = 6
Output:
0 2 6
Explanation:
0 is the product of 0 and 1.
2 is the product of 1 and 2.
6 is the product of 2 and 3.


Example 2:

Input:
N = 56
Output:
0 2 6 12 20 30 42 56
Explanation:
0 is the product of 0 and 1.
2 is the product of 1 and 2.
6 is the product of 2 and 3.
12 is the product of 3 and 4.
and so on.

You don't need to read input. Your task is to complete the function pronicNumbers() which takes an integer N as input parameter and returns a list of integers.
