Find all Critical Connections in the Graph
Welcome to the daily solving of our PROBLEM OF THE DAY with Yash Dwivedi. We will discuss the entire problem step-by-step and work towards developing an optimized solution. This will not only help you brush up on your concepts of Graph but also build up problem-solving skills.
In this problem, you are presented with an undirected connected graph consisting of n vertices and connections between them represented by an adjacency matrix. Your objective is to determine whether it is possible to start traversing from a node, x, and return to it after traversing all the vertices at least once, using each edge exactly once.
Example :
Input:
paths = 0 1 1 1 1
1 0 0 1 0
1 0 0 1 0
1 1 1 0 1
1 0 0 1 0
Output: 1
Explanation:
One can visit the vertices in the following way:
1->3->4->5->1->4->2->1 (assuming 1-based indexing) Here all the vertices has been visited and all paths are used exactly once.
Give the problem a try before going through the video. All the best!!!
