Leetcode 1424. Diagonal Traverse II
Return the elements of a possibly jagged 2D array in diagonal (anti-diagonal) order, where cells on the same diagonal share the same i+j value and diagonals are output by increasing i+j. The key challenge is grouping elements by diagonal index and preserving the required within-diagonal ordering while handling irregular row lengths.
