Solving LeetCode Problems Using Graph Theory by Ilia IvankinApril 18th, 2024 Too Long; Didn't ReadGraphs model pairwise relationships with vertices and edges. Trees are connected acyclic graphs. DFS explores deeply using a stack, useful for pathfinding and connectivity. BFS explores level by level...
Course Schedule, Longest Increasing Path in a Matrix and Alien Dictionary. Note that some of the tree problems can also be asked in n-ary tree format, so make sure you know what an n-ary tree is. Note: The last problem may be quite tricky to solve, so feel free to skip that one....
Trees and Graphs Tree is a special type of graphs, so the two usual techniques used to traverse a graph are also applicable to trees. We recommend: Binary Tree Inorder Traversal, Populating Next Right Pointers in Each Node and Number of Islands. Note that some of the tree problems can als...
The efficiency of Union Find makes it suitable for problems in graph theory, such as detecting cycles in undirected graphs or finding connected components. Sample Problem **Problem:**200. Number of IslandsGiven anm x n 2D binary grid grid where 0 represents water and 1 represents land, and ...
