An adjacency list is simply an unordered list that describes connections between vertices. The size of the array is equal to the number of vertices. Adjacency List: An array of lists is used. An entry array[i] represents the list of vertices adjacent to the ith Vertex. If for any cell (i, j) in the matrix “ mat [i] [j] = 1 “, it means there is an edge from i to j, so insert j in the list at i-th position in the array of lists. Output: The adjacency list is: g[i][j]=1 and g[j][i]=1 if both the vertices i and j exists. Up to O(v2) edges if fully connected. Examples: Input: arr[][] = [ [0, 0, 1], [0, 0, 1], [1, 1, 0] ] brightness_4 Minimum sub-array such that number of 1's in concatenation of binary representation of its elements is at least K, Minimum steps required to convert X to Y where a binary matrix represents the possible conversions, Find if there is a path between two vertices in a directed graph, Data Structures and Algorithms – Self Paced Course, We use cookies to ensure you have the best browsing experience on our website. 2 -> 1 -> 3 Adjacency List. 03, Jan 21.
