Solution: Pascal’s Triangle

Explore how to implement Pascal’s Triangle generation using a dynamic programming approach. Understand how each row builds upon the previous one by summing adjacent values, ensuring efficient computation and proper handling of boundary conditions to solve this classic coding interview problem.

Statement

Given an integer, numRows, generate the first numRows of Pascal’s triangle.

In Pascal’s triangle, each element is formed by adding the two numbers directly above it from the previous row. The triangle starts with a single 11 at the top, and each row expands based on this rule.
