Solution: Pascal’s Triangle

Explore the dynamic programming approach to generate Pascal’s triangle by building each row based on the previous one. Learn how to initialize boundary values and compute interior elements efficiently while understanding the time complexity of O(numRows²) and constant space usage.

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.
