Pascal's Triangle Generator Lab

Easy
20.0% Acceptance

In this lab, you will implement a function to generate the first numRows of Pascal's Triangle. Pascal's triangle is a triangular array of numbers in which each number is the sum of the two numbers directly above it, as shown in the image below:

Your task is to write a function generate that takes an integer numRows and returns the first numRows of Pascal's Triangle in a nested array format.

Examples

Example 1:

Input: numRows = 5
Output: [[1],[1,1],[1,2,1],[1,3,3,1],[1,4,6,4,1]]

Example 2:

Input: numRows = 1
Output: [[1]]

Example 3:

Input: numRows = 3
Output: [[1],[1,1],[1,2,1]]

Constraints

  • 1 <= numRows <= 30

Challenges

  1. Implement the generate function.
  2. Export the generate function using ESM export.
