🧠 Question Description
In this LeetCode problem (#118 - Pascal’s Triangle), you're asked to generate the first n rows of Pascal’s Triangle. Each row contains numbers where each element is the sum of the two elements directly above it in the previous row. This problem tests your understanding of combinatorics, loop constructs, and dynamic list formation. Efficient solutions can leverage direct formulae like binomial coefficients (nCr) or simple iterative building. It’s a classic problem frequently asked in coding interviews and helps strengthen foundational DSA concepts such as arrays and nested loops. A must-practice for FAANG and other top tech interviews!
