Pascal's Triangle Problem Statement

You are provided with an integer N. The objective is to return a 2-dimensional list representing Pascal’s triangle up to row N.

A Pascal's triangle is a triangular array where each entry is the sum of the two entries directly above it in the previous row, representing binomial coefficients.

Example:

Input:

N = 4

Output:

[[1], [1, 1], [1, 2, 1], [1, 3, 3, 1]]

Constraints:

• 1 ≤ T ≤ 40
• 1 ≤ N ≤ 50

Note: You do not need to print the list; just return the 2-dimensional list from the function. Each test case should be independently computed.
