Snake (Boustrophedon) Traversal

Snake (Boustrophedon) 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. Reverse every odd-indexed row. 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 rows in snake order: row 0 left-to-right, row 1 right-to-left, alternating. One line, space-separated.

Input

1 1 -11

Output

-11
  • •1 <= M, N <= 8.
