Solution: Pascal’s Triangle

Explore how to generate the first numRows of Pascal’s triangle by applying dynamic programming principles. Learn to iteratively construct each row from the previous one, ensuring boundary values remain one and computing interior values through summation of elements above. Understand the time and space complexity of this approach and how dynamic programming optimizes the calculation by reusing computed states.

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.

Constraints:

  • 1 ...
