Anti-Diagonal Traversal
Anti-Diagonal Traversal
MediumArrays0% accepted
Your solve(...) function receives these inputs directly as ready-made arguments — no input reading or parsing needed. Just compute and return the answer. Group by i+j. Input: first line two integers M and N; next M lines each with N integers. You are given solve(m, n, grid) where grid is an M x N 2D array.
Approach
Print elements grouped by anti-diagonals (cells with the same i+j), diagonals in increasing order, and within each diagonal by increasing row index. One line, space-separated.
