Number Pattern Program

Write a program that takes an integer N as input and prints a specific pattern for N lines.

Example:

Input:

N=3

Output:

[[1, 2, 3, 10, 11, 12], [4, 5, 8, 9], [6, 7]]

Explanation:

For N=3, the pattern is created as follows:
First row: 1 2 3 10 11 12
Second row: 4 5 8 9
Third row: 6 7
Each list within the 2D list represents a row in the pattern.

Constraints:

• 1 <= N <= 1000
• Time Limit: 1 second
