WebJan 27, 2024 · Given a Grid of size NxM, and two integers X and Y, the task is to count the minimum number of rows between the row containing X and the row containing Y in such a way that the adjacent rows in between them have at least one element in common. Multiple occurrences of a number are allowed in the grid. In other words, two rows are said to be … WebMay 6, 2024 · Approach: We can either use BFS or DFS for this purpose. Set 1 of this article implements the DFS approach. In this article, BFS approach is used. We do BFS from a given source. Since the given graph is undirected, all the vertices that belong to the disconnected component are non-reachable nodes.
