Dfs in a matrix

WebGiven an N × N matrix of positive integers, find the shortest path from the first cell of the matrix to its last cell that satisfies given constraints.. We are allowed to move exactly k steps from any cell in the matrix where k is the cell’s value, i.e., from a cell (i, j) having value k in a matrix M, we can move to (i+k, j), (i-k, j), (i, j+k), or (i, j-k).

WebJun 8, 2024 · This is the most simple implementation of Depth First Search. As described in the applications it might be useful to also compute the entry and exit times and vertex color. We will color all vertices with the color 0, if we haven't visited them, with the color 1 if we visited them, and with the color 2, if we already exited the vertex. WebJun 11, 2024 · Adjacency Matrix. Adjacency list is a list of lists. Where each list is a vertex and its corresponding edges therein. The advantage of a list over matrix is that list consumes less space. Matrix takes O(v²) space requirement. Queries are pros for matrix because finding one vertex to another takes O(1).
