Leetcode 2675. Array of Objects to Matrix
Convert an array of objects into a 2D matrix by extracting a header row of all unique keys (in a specified order) and aligning each object's values into subsequent rows under the corresponding columns, inserting placeholders for missing keys. The challenge is to efficiently collect and order keys, map them to column indices, and populate the matrix for potentially large inputs while preserving the required column ordering.
