Graphs are a fundamental topic in computer science and are widely used in various applications.
Explain the Problem Implement the Breadth-First Search (BFS) algorithm for graph traversal. Given a graph and a starting vertex, traverse the graph in breadth-first order and print the vertices in the order they are visited. Example: Input: Graph: 0...
Explain the Problem Implement the Depth-First Search (DFS) algorithm for graph traversal. Given a graph and a starting vertex, traverse the graph in depth-first order and print the vertices in the order they are visited. Example: Input: Graph: 0: [1...
Problem Statement Given a directed acyclic graph (DAG), find all paths from the source node (node 0) to the target node (the last node). The graph is represented as an adjacency list where graph[i] is a list of all nodes i can directly reach. Example...
An image is represented by an m x n integer grid image where image[i][j] represents the pixel value of the image. You are also given three integers sr, sc, and color. You should perform a flood fill on the image starting from the pixel image[sr][sc]....
Given an m x n 2D binary grid grid which represents a map of '1's (land) and '0's (water), return the number of islands. An island is surrounded by water and is formed by connecting adjacent lands horizontally or vertically. You may assume all four e...
Example 1: Input: beginWord = "hit", endWord = "cog", wordList = ["hot","dot","dog","lot","log","cog"] Output: 5 Explanation: One shortest transformation sequence is "hit" -> "hot" -> "dot" -> "dog" -> cog", which is 5 words long. Example 2: Input: ...
