Nvidia SDE OA 2025 | Semiconductor Signal Routing & Parallel Trace Routing

Problem 1 - Semiconductor Signal Routing Problem Statement You are given an N × M grid of integers representing a semiconductor routing matrix. You start from cell (0, 0) and must reach cell (N - 1, M - 1). You may move in four directions: Up Down Left Right The quality of a path is defined as the Bitwise AND of all cell values present on that path. Find the maximum possible path quality. Constraints Constraint 1 ≤ N, M ...
