Description

Pascal’s Triangle Visualization
This visualizer demonstrates how Pascal’s Triangle is built using dynamic programming. Each element is computed as the sum of the two values directly above it, representing the binomial coefficients. It helps understand recursive relationships, combinatorics, and the DP approach to constructing the triangle efficiently.
